Going through some documentation, it appears as though you can restore a backup from 2.0 to 2.4 and there are upgrade files and paths dedicated for this move.
When trying the same from 2.0 to 2.6, the document for 2.6 here states "Cisco ISE, Release 2.4 supports restore from backups obtained from Release 2.0 and later"
Since there are no files for upgrading from 2.0 to 2.6, can I assume that a backup-restore for the same is unsupported?
