The time required to upgrade from Avaya IR R1.0, R1.2, R1.2.1, or R1.3 to Avaya IR R2.0 on the same platform is approximately 1 hour, 30 minutes.
Important:
The tsc and craft login home directories are removed during an upgrade from R1.0, R1.2, R1.2.1, or R1.3 to IR R2.0. To preserve the contents of these directories, back up the /export/home/tsc and /export/home/craft directories before beginning the upgrade process.
