Thanks a lot for help! Reality looks a bit different. It was 4.1.4 -> 4.3 upgrade. It was merging procedure while first 4.3 startup. Looks fine. But, when I'm trying to install XAR as proposed on a sub-wiki, it says me, that it is already installed on main wiki and gives no options to install it on sub-wiki.

But I didn't merge conflicts on subwikis yet (as far as I remember). Am I missing something?

Thanks, fixed a typo ;) Will do it one by one now. I'm lucky to have less then 10 subwikis to upgrade at this stage. :-)))))) Yea. Distribution Wizard is a bit young and we don't have much tools to migrate from pre Extension Manager subwikis yet.

XEM 4.1.4 -> XEM 4.3 upgrade. Main wiki upgraded fine with the help of upgrade manager on the first run. What is the correct way to upgrade each and every subwiki's UI?

For the main wiki it's a special case because the WAR comes with a default UI information. it's not too painful to take care of theses wikis one by one (just this time) you can go to each one and install with Extension Manager the XAR extensions you need (for XE use the advanced search and search for org.xwiki.enterprise:xwiki-enterprise-ui and 4.3 version). You will then get the same installation UI you got in the Distribution Wizard for the main wiki with conflict resolution etc. be a bit more tricky and will imply some scripting since there is required backend to automate all this but not much UI yet. >The next time, the Distribution Wizard will list you the outdated extensions from all wikis in a second step and you will be able to upgrade them from there like for the main wiki in the first step.
