Is there some info how to reset the data for migration? I’ve got the same problem but i don’t have a snapshot or possibility to rollback to 10.11 and restart the upgrade process.
Removing /var/lib/xwiki/data/store and inserting the last backup from 10.11 /var/lib/xwiki/data/storage does not retrigger a migration on restart of tomcat.
Do I have to do something else to re-trigger the migration? Setting the version in the table xwikidbversion did not work either…
The currently released 11.0.1 has some retry (but it might be skipping the specific document on which the migration failed).
It will in 11.0.1. The problem is that in 11.0 the migration is totally skipped if it started in a previous run.
I’m also interested in without restoring the wiki.
Are the folder names generated randomly or is there a pattern like hash function? Probably we can write a script which will move the old files to the new location.
That’s what the migration does but in 11.0 it crash when hitting a deleted attachment. See https://jira.xwiki.org/browse/XWIKI-16076.
11.0.1 is now released (on Debian repository too). If you have a partially migrated 11.0 the best if to reset to previous data but if you cannot then you should make sure the version in the database (table xwikidbversion ) is just lower than 1100000, like 1099999 (so that it’s triggered) before starting XWiki.
It might still miss the specific document on which the 11.0 migration failed.
First, I would like to thank you supporting us.
I just installed the 11.0.1, but now I’am getting a huge amount of errors:

Phew! Thank you very much for your effort. I finally got my Wiki working again…
These were the steps to get the migration working:
- update table xwikidbversion to 109999
- copy backup of file storage to /var/lib/xwiki/data/storage
- don’t move or remove the partially migrated file store under /var/lib/xwiki/data/store
- start the upgrade via apt
- finish the flavor upgrade
- done
I got the same migration failed errors as before when i missed copying the backup of the old storage to /var/lib/xwiki/data/storage
That’s weird it should not be needed.
- copy backup of file storage to /var/lib/xwiki/data/storage
- don’t move or remove the partially migrated file store under /var/lib/xwiki/data/store
It’s not very clear to me what you exactly mean, if you have a pre migration back to restore you should not keep the partially migrated store.

Note that if you tried a previous SNAPSHOT jar apt/dpkg won’t touch it so you need to remove it by hand to make sure it’s not the one used instead of the 11.0.1 one.
OK that one definitely look like 11.0.1. Checking what this means.
Crap I know why @jmit had to restore an old /var/lib/xwiki/data/storage. I made a mistake in the retry code.
So as a workaround try to create /var/lib/xwiki/data/storage folder and put some file in it (it does not matter as long as it’s not empty).
11.0.2 on the way…
11.0.2 released
Wow!!
Should I set the xwikidbversion <11 before updating again?
It’s not my day, I fixed the issue but did not merged it in the 11.0.x branch. 11.0.3 ready soon…
11.0.3 available 
I have a partially migrated XWIKI. Is it possible to continue, if Destination already exists exception occurs? Obviously, the script will end up in a loop and tries to move the same file.

Have you restored some backup ? The migration only do moves so it should not be possible to end up in a state where both the old and new folder exist (unless it was killed in the middle of the move which is not really the situation here AFAIK).
You should have an INFO log (some thing like Moving document folder [/var/lib/xwiki/data/store/file/xwiki/Some/Document/~this] to new location [/var/lib/xwiki/data/store/file/xwiki/3/f/2f12c44348abc0098a4db3722d7732]) before this error indicating which move it was trying to do. Could you check what you have exactly in both folders so that we know if we should moved content to the old or new location before starting again the migration.
