XF 2.2 password issues after vb5 import

[jtorral]

So migration test went fairly well. Went from vb5 to latest xf on a trial server. Having a few members do some testing. However, everyone needs a password reset.

Did I miss something in the migration?

Thanks

Not sure... but the "latest" import from vBulletin may not be supported.
There may be issues if the latest XF import does NOT support the latest vB version.. which would NOT be unheard of since I am sure there is a variance between current vB versions and XF.
You did not specify which version of vB you imported from.... their "latest" is probably not currently fully supported since they make schema changes in the DB that have to be adjusted for.

Was the VB5 forum itself an import?

Can you check the password hashing scheme used, in the VB5 database?

vbulletin 5 has 4 available password schemes

• argon2id
• blowfish:15
• blowfish:10
• legacy

I don't think xenforo authentication scheme covers them all

The importer currently supports blowfish and argon2id.

Can you check an affected account to see what is in use in the VB DB.

You are currently running vBulletin version 5.6.8.
Dont know what has they are using

ok. so i am going to try the import again. Any suggestions on being able to getthe passwords migrated properly?

If an unsupported hash is in use then another import won't help.

I found this

With PHP 7.2 and higher with the Argon library installed, vBulletin 5.6.2 will use the Argon2id password hashing scheme. Without the Argon library installed, it will use the Blowfish password hashing scheme with a cost of 15.
