Umbraco 13 to 17 is not a routine package bump. Here is what actually breaks at each version – the backoffice rewrite, removed property editors, the JSON serialization change – and a practical strategy for getting through it without surprises.
A professionally built Umbraco website typically costs somewhere between €15,000 and €100,000+, depending mainly on integrations, design, content migration, languages and accessibility requirements.
However, that the range is useless without context. A straightforward marketing site, and a multilingual platform connected to an ERP are technically both “Umbraco websites”, but they are not remotely the same project.
Umbraco sells extended support for version 13 in 6, 12, or 24-month blocks - but does not publish the price. Here is the full cost of each route: the XLTS fee structure and what it quietly excludes, versus what an upgrade to 17 actually involves.
