Hello,
on 2 Virtual Machines with Debian : testing one XWiki 14.10.11 and one XWiki 15.4, I have been able to import a Space from Confluence (which was not working yet, using the Confluence Migrator extension along with Pro Macros).
On the version 14.10.11 Pro Macro in test still active the result was not too bad. We however ended with the following errors on some macros (3 errors on one Space)
[livesearch]
[contentbylabel]
[popular-labels]
Here is a sample with one of the error messages produced:
Do you have any thoughts about it?
I would again test the manuel method on 15.4.
