Migration of Database from ARIS 7 to ARIS 10

Hi all,

I have a series of databased (.adb format) which needs to be uploaded onto ARIS 10 thin client.

When I upload the databases, I'm getting an error message that says 'Unable to import database. The ADB file to be restored originates from an invalid version. Restoring this content is not supported.'

Can anyone help me out, if they've come across this issue?

Thank you,
TJ
