Help / Discuss
#1

Hi, I have very old instalation of XWiki (2.2…) There is a lot of data and I need to migrate it to the newest XWiki.
Can you give me some advice how can I do it? I don´t know if exist some conversion or migration tool? And export to XAR file isn´t in 2.2.

Or can I make some step by step upgrade?

Thanks for any advice.

You could try to install some XAR export extension from extensions.xwiki.org and see if it works.
