What if the upgrade fails? What are the steps? Thanks - Karen

Restore from backup is the only option.

That's what I thought but figured I'd ask. Thanks!

If you are running virtually, you can make a snapshot. That is the fastest way to recovery

The answer is very dependent on your infrastructure and system design. I'll summarize the general process we use, but providing a detailed reversion plan would be impossible without being familiar with your infrastructure.
If you have virtual infrastructure, you might first clone the various servers into a development environment, and adjust the configurations so everything works in dev. The dev environment should not be able to reach the prod environment. You wouldn't want your dev JBoss server to accidentally connect to your production database server, or your dev Linklogic server to pull prod HL7 messages into dev. When dev is working, do the upgrade and test. This part is optional of course, but it is likely to show you some unexpected issues that you'll want to prepare for with the prod upgrade.
When ready for the production upgrade you can snapshot the JBoss server, database server, and terminal servers if you use them. Go through the upgrade steps, and if there is a problem, revert to the snapshots.
In a smaller environment, assuming all server roles are on physical servers, you might back up the SQL database, back up JBoss config, back up other essential data and configurations (sorry for lack of detail--it has been several years since I've had to go this route). Go through the upgrade, and if there is a problem, restore the database, reinstall the old JBoss, reinstall the old CPS client software and plugins, and probably other stuff I'm forgetting.

This is perfect. Thank you very much. We actually have someone we trust very much assisting with our upgrade and I just want to make sure I'm asking the right questions.
We are going to upgrade our test environment first and then about 4 wks later production. This was very helpful.
