Replace ASA primary unit

[kzhen]

The ASA 5540 primary unit is totally dead. Now the seconday is active now. While waiting for the RMA from Cisco. It is my first time to replace the ASA. I have the following questions:

1. should the version of replacement ASA be the same as the current one? The current one is running 7.2.3

2. I can't find any doc. from Cisco. What will be the steps for replacement?

3. Will it affect if I replace during the production time?

Please advise
