I think you need to download all with the force flag
I have run into this before, it is very important to only restore on same versions. It can take hours of tinkering to get it right. Essentially now you are trying to downgrade the FreePBX. You made it worse by backup up webroot.
Also consider it still may not work as database schema changes between updates.
I would almost download the tarball of the version you are trying to restore from and do an install_amp. It will detect the existing installation and simply copy the modules. Make sure you do an rm -fr /var/www/html/admin/* prior to running install_amp
Make sure you have good backup before doing any of this.
Things that are going to snag you.
AMPDB not restored
Backup profiles stuck and using 100% CPU (see top)
Asterisk not starting due to presence of cel config files
Hi Skyking,
Thats a great answer. Someone who has experienced the same problem.
Finally I think it is the most simple solution to update both PBXs to the latest modules before backup>restore.
This will take less time and complexability for migration.
Thanks
