Umbraco 7 has been end-of-life since September 2023. Umbraco 8 since February 2025. There is no direct code upgrade. We will tell you what content can come across, and whether Umbraco 17 is still the right home.

Upgrade or move
The site still works. That is why it has been left alone.
Umbraco 7 and 8 are classic ASP.NET / .NET Framework CMS installs. From 9 onward the product is ASP.NET Core. A lot of the sites we hear about were built when Grid Layout, Nested Content, and a handful of packages were the CMS. Then the person who understood the Document Types left.
You might recognise one of these:
You do not need a new brand, or a WordPress pitch. You need a clear read on the install you already have.
Umbraco is still a real product. The current long-term line is Umbraco 17, on .NET 10. The problem is not that HQ vanished. It is two framework breaks between you and that line, and no in-place climb.
HQ’s upgrade docs say it in those words. 7 to 8 was a product rewrite. 8 to 9+ changed the web framework from ASP.NET to ASP.NET Core. Content can be migrated. Templates and custom code are reimplemented. The documented v8 database path goes 8 → 10, then major to major toward current. A v7 site is not “one upgrade”.
Forms, Deploy (Courier is end-of-life), commerce, and community packages must exist on the target major. Nested Content, Grid Layout, and macros were removed in 14. The AngularJS backoffice went in 14. A “jump to latest” from v8 is also a rebuild of the editor experience. SQL CE, common on old 7/8 sites, has no official migration path to v10+.
13 is an LTS in its security phase. It ends 14 December 2026. Do not land a project there unless you are using it as a short stepping stone. Umbraco 17 is the current LTS — released November 2025, on .NET 10, end of life 27 November 2028. Umbraco 18 is an STS with a 2027 end date; 16 already ended in June 2026.
After end-of-life, HQ ships no security patches, bug fixes, or official support. They do not recommend hosting on those majors. They do not remotely switch an on-prem site off. Extra long-term support is a paid security-and-compliance bridge — v7 through 1 January 2027, v8 through 24 February 2027 — not a strategy. Cloud end-of-service is later (v7: 1 January 2028; v8: 24 February 2028). After that window, Cloud stops hosting. That is a hosting clock, not “Umbraco dies that day” for every install.
Old Ucommerce Classic is not Umbraco Commerce. Umbraco Commerce is the Vendr product, renamed after HQ acquired Outfield Digital. Vendr 3 itself ended 29 June 2024. If the site sells through Ucommerce, that is a second migration. We will not treat them as one product.
None of that makes the content or the information architecture worthless. It does mean “upgrade v8 to 17 over a weekend” is the wrong first move.
We start with the install, not with a destination.
Version, Document Types, Grid / Nested Content / macros, packages, commerce add-on, SQL CE or SQL Server, and whether the site is on Cloud or on-prem. We will tell you what content can migrate, and what has to be rebuilt.
There are three honest outcomes. We recommend one, not all three.
Content, URLs, and the pages people actually use come across. Templates, Angular extensions, and packages that have no target-major equivalent do not.
Source, a short record of what changed, and a site someone else can understand.
We will not tell you Umbraco 13 is the place to land. We will not tell you WordPress is the answer to every 7/8 site. If you already know you want to stay on Umbraco forever, an Umbraco-only partner may be a better fit. If you want an honest fork in the road, talk to us.
A URL and a rough version is enough to start.
The first call is 30 minutes. You leave with a recommendation you can take to a manager, not a rebuild estimate pulled from thin air.
We have taken over and modernised ageing .NET systems for Australian organisations, including work with Data#3, Hastie, NESS, and NSW Health. That is related Microsoft web work, not a published Umbraco 7/8 → 17 case study. An Umbraco 7 or 8 install still starts with its own assessment. We will not pretend it is a project we have already published.
Thirty minutes. Bring a URL and a version number if you know it. We will tell you whether to rebuild on 17, leave Umbraco, or buy time — and we will not pretend 13 is a long home.
