In January 2025, Trend Controls withdrew all support for the 963 Supervisor — the web-based front-end platform that has managed BMS installations across thousands of UK commercial buildings since the mid-2000s. No more security patches, no software updates, no technical support. If your building currently runs on Trend 963, you are now operating unsupported software with known vulnerabilities and no path to resolution short of upgrading.
This guide explains what the end of life means in practice, what your upgrade options are, and how a migration to Trend IQVISION works — including what you can keep and what needs replacing.
End of life means Trend will no longer issue software updates or security patches, provide technical support for 963-related issues, supply new licences or additional user seats, or guarantee compatibility with current operating systems. Windows 11 and Server 2022 are already known to cause issues with certain 963 configurations, and that compatibility gap will widen with every OS update that ships.
In practical terms, your 963 installation will continue to function for now — but each passing month increases the risk. Cybersecurity vulnerabilities go unpatched. If the server running 963 fails, restoring it on current hardware may not be straightforward. And any software fault that emerges is now permanently unresolvable without the vendor.
There are also compliance dimensions worth considering. The UK's NIS Regulations 2018 impose a duty on operators of essential services to take appropriate and proportionate measures to manage the risks posed to network and information systems — which includes keeping software patched and supported. The NCSC's guidance on vulnerability and patch management explicitly identifies running unsupported software as a high-risk configuration. For buildings in healthcare, education, or data centre environments where BMS failure has direct operational consequences, cyber insurance underwriters are increasingly scrutinising whether supervisory software is within vendor support — and some are declining or repricing cover where it is not. A 963 migration isn't just a technical upgrade; for many building owners it's a risk management decision that can't be deferred indefinitely.
IQVISION is Trend's current supervisor platform, replacing 963 as the front-end for Trend BMS installations. It is built on the Niagara 4 framework (from Tridium), which is the industry-standard open platform used by most major BMS manufacturers including Honeywell and Johnson Controls. Key characteristics:
There is no single right approach to migrating from 963 — the best option depends on the age and condition of your field infrastructure, your budget, and your operational requirements.
This is the most common and cost-effective approach for buildings with IQ3 or IQ4 controllers in reasonable condition. The 963 supervisor server is decommissioned and replaced with an IQVISION installation (on a new server, VM, or cloud instance). The existing IQ field controllers are retained and re-pointed to the new supervisor.
The migration involves:
The graphics rebuild is typically the most labour-intensive element. Simple mimic diagrams can be recreated efficiently; complex custom graphics pages take longer. Alpha Controls uses templated IQVISION graphics libraries for common plant items (AHUs, FCUs, chillers, boilers) which significantly reduces rebuild time.
Where some field controllers are old, failing, or no longer fit for purpose, a 963 migration is a natural opportunity to replace them alongside the supervisor upgrade. This avoids a second mobilisation in 12–18 months when ageing controllers fail independently.
IQ2 controllers (from early-2000s installations) in particular are worth replacing during a supervisor migration — they are no longer supported and have limited I/O flexibility compared to modern IQ4 hardware.
For buildings with very old infrastructure, persistent faults, or where the opportunity exists to improve controls capability substantially, a full replacement may be the right choice. This involves new IQ4 or IQ4NC controllers throughout, new field wiring where needed, and a complete IQVISION installation.
Full replacements take longer and cost more but deliver the best long-term outcome — a fully supported, modern BMS with a 15–20 year forward lifespan. Approved Document Part L requires that heating and cooling control systems in commercial buildings include weather compensation, optimum start, and time scheduling — all of which the Trend 963 supervisor supported but which must be verified as correctly configured during an IQVISION migration; a supervisor upgrade is the right moment to audit control strategies against Part L requirements. CIBSE Guide H defines the functional requirements for BMS supervisors — graphical overviews, alarm management, trend logging, and schedule management; the IQVISION platform meets current Guide H expectations for a modern supervisor, while the 963, now without security updates, does not meet the cybersecurity requirements that Guide H increasingly references. They also provide the opportunity to add functionality that was not possible on the original installation: sub-metering, demand-controlled ventilation, weather compensation, and BACnet integration with third-party equipment. For a guide to the specific challenges of upgrading controls in older buildings — including what to survey, what to retain, and what to replace — see our article on retrofitting BMS in legacy buildings.
This is the question most 963 users ask first. The honest answer is that 963 graphics cannot be directly imported into IQVISION — the two platforms use entirely different rendering technologies (Java applets vs HTML5). Graphics must be rebuilt.
However, this is not necessarily the loss it sounds like. Most 963 installations have graphics that were built years ago, reflect plant that has since changed, and were never particularly intuitive to navigate. A migration is an opportunity to build better, cleaner graphics that match the current state of the building and are genuinely useful to operators.
Historical trend data from 963 can typically be exported in CSV format and archived. It does not import into IQVISION, but it remains accessible for reference. Going forward, IQVISION's trend logging provides more flexible data retention and export options.
Timeline depends on the size and complexity of the installation:
Alpha Controls plans migrations to minimise disruption to building operations. Where buildings are occupied, we schedule cutover work outside core hours and maintain manual control capability throughout the transition period.
A supervisor-only migration (Option 1) for a typical medium-sized office building typically ranges from £8,000–£25,000 depending on graphics complexity and the number of controllers. Partial or full infrastructure refreshes are priced based on the controller count and scope of new equipment. For broader context on what BMS upgrade and retrofit projects cost, see our guide to BMS retrofit costs in the UK.
The cost of not migrating should also be factored in: an unsupported supervisor running on ageing hardware is a single-point-of-failure. Emergency recovery of a failed 963 installation — if possible at all — is significantly more expensive than a planned migration.
Alpha Controls are Trend-certified engineers with extensive experience migrating 963 installations to IQVISION across London and the South East. We have delivered migrations in occupied commercial offices, healthcare facilities, education buildings, and multi-tenanted developments — all without unplanned loss of HVAC control. If you're also considering whether to stay with Trend or evaluate alternatives, our comparison of Trend vs Distech vs Siemens BMS sets out the practical differences between the main platforms.
Our migration process includes a pre-works survey to document the existing installation, a fixed-price proposal, phased on-site delivery, and post-migration training for your facilities team on the IQVISION interface.
We cover London, Kent, Surrey, Essex, and across the South East. Contact us to arrange a site survey, or request a quote for your 963 migration.
Technically yes — the software will not stop working on 14 January 2025 or any specific date. But without security patches, cybersecurity risk increases over time. Without OS compatibility updates, a future Windows update could break the installation. And without vendor support, any software fault becomes permanently unresolvable. Most building owners are treating this as a 12–24 month migration window rather than an indefinite deferral.
In most cases, no. IQ3 and IQ4 controllers communicate with IQVISION natively. IQ2 controllers from very early installations may need replacing, but this is assessed on a case-by-case basis during the pre-works survey.
Yes. Alpha Controls regularly takes over Trend systems originally installed by other contractors and carries out migrations. We can work from existing documentation or survey the installation from scratch if documentation is unavailable.
Both options are available. On-premise deployments use a dedicated server or VM within your network. Cloud-hosted deployments use a Niagara 4 instance on Azure or AWS, accessible from anywhere with an internet connection. Alpha Controls advises on the right deployment model based on your IT infrastructure and security requirements.
