Migrate 9.10 to 11.2 freenas

Hi all
Have been trying for the last week or so to migrate from 9.10 to 11.2 on Freenas.
I have tried to copy paste so file that I thought were the correct one to find they weren’t.
Can some point me to the correct location of UrBackup database?
So when I copy paste all I need to do is just start the new iocage jail and it will continue from the old if possible.

Thanks in advance
any yes I have use the google search and a hell of alot of other search option with no luck at all.

I must say this is ridiculous I have copy pasted over var/urbackup and urbackup/urbackup and it still doesn’t show my clients.
None of the old setting have moved across. What am I missing?
