Versions from which you can upgrade
SDL Tridion Sites supports only a specific set of upgrade paths to upgrade to SDL Tridion Sites 9.1. The upgrade paths also depend on the type of upgrade you want to perform: a rolling upgrade or a non-rolling upgrade.
- SDL Tridion Sites 9
- SDL Web 8.5
You cannot upgrade to SDL Tridion Sites 9.1 GA from SDL Tridion Sites 9 Cumulative Update 1. If you are running SDL Tridion Sites 9 Cumulative Update 1, contact SDL Customer Support to get the latest hotfix release of SDL Tridion Sites 9.1 instead.
If you perform a rolling upgrade, you can only upgrade to the current version of SDL Tridion Sites from SDL Tridion Sites 9.
You can also upgrade the add-on products compatible with these versions. For example, SDL Content Porter 8.5 is compatible with SDL Web 8.5.
