Alfresco CE : upgade issue - Failed to create store root

[PoF]

Hello,

I'm looking for some help 

I'm trying to upgrade an ACS CE full in docker from 6.1.1 to 7.2.

I'm following official doc: 
- dump db backup alf_data
- install a fresh new Alfresco in 7.2
-check everything is 
-stop & restore (db + alf_data)

But in one of my platform i'm facing an issue.

I retried several time  always same message:

On many previous i can see that i need to revert and retry.

ALF in version 6 is working fine.

I already upgraded many other platform without any issues.

I'm probably missing a file or an entry in DB.

Can i setup some DEBUG logs to find what is missing ?

Thanks in advance .
