rollback (see:
Migration procedure:
1. Connect a USB 2.0 DVD drive to the Extended Communication Server
2. Introduce the Extended Communication Server R4.2 DVD in the driver
3. Reboot the Extended Communication Server
By default, the Extended Communication Server boot sequence is:
a. DVD
b. Hard disk
The Extended Communication Server reboots from the DVD, the migration welcome page
is displayed.
4. Validate the migration option. If you do not validate within 60 seconds, the Extended
Communication Server boots on hard disk (release 4.1) and the migration process is
canceled.
When the migration option is validated, the Extended Communication Server performs:
• A copy of the database to the /home directory
• The Extended Communication Server R4.2 software installation
This installation spends several minutes.
A reboot is required.
