We've done the 6.x to 9.0 migration by our own way of scripting, not openupgrade.

It's is entirely possible, just no one has written the script.

Hi Holger, Thanks for the answer,

I'm wondering if moving password column to password_crypt even if the two odoo versions (6 and 9) are using different hash modules, will work properly.

Did you try moving it from v6 directly on v9 using OpenUpgrade ?

As much as I know, OpenUpgrade migrates data from version 'n' to version 'n+1', so it's impossible for openupgrade to migrates from 6 to 9 directly.

Can you confirm that ?

Thanks a lot.

lot like it generates hashes that passlib used in
blob/9.0/addons/auth_crypt/ might just understand. Did you 
ever try to simply move the password column to password_crypt? This might just 
work. I even think I remember to have done exactly that:

[The rest is quite academic, because the above is your solution. But given I 
wrote this text already, I won't delete it] If not, you'll have to take the 
hash apart (separate magic and salt from the hash, split by the dollar sign) 
and craft one passlib understands. If this is not possible (which I doubt), 
you'd have to keep the old hashes in some separate column, and for every login 
check if there exists an old hash, verify it with the v6 code, and write a new 
hash v9 style. Don't forget to clear out the old hash column then.
But still, my guess would be that renaming the column suffices.
