2. When the GC2E arrives, remove the communicator card from GC2 and install the same in GC2. Power up the GC2E
4. Request customer service to push the backup to the new panel.
You are correct in all ways except for when to power up. If you are requesting a backup and restore, be sure to not power up the new panel with your module in it until you have requested the settings pushed and our team confirms it is time to power up in email reply.
If you power up before we push the backup, the new panel may sync its device list (an empty one) and overwrite the backup before it can be pushed down.
