I recently did a 7.2 -> 7.4.2 upgrade and a 7.3 -> 7.4.2 upgrade. I had to do a document for my client. See attached. Let me know if you have any questions.
I will watch this thread
BL_Upgrade_BL_7_3_to_7_4_2.doc 552.0 K
is this doc just for oracle ?
The last upgrade I performed for a customer was from 7.3.0 to 7.4.1.
In my experience, there are two issues to keep your eyes open for.
Keep in mind that I did the upgrade the day 7.4.1 was released; these issues ARE PROBABLY FIXED at the time of this writing. So before doing the upgrade, call support, and find out if you even have to watch out for these two gotchas.
Having said that, here's what I ran into.
First, I had to upgrade from 7.3.0 to 7.4.0 to 7.4.1. This is a bit more work than going straight from 7.3.0 to 7.4.2. More importantly, 7.4.0 is not generally available. AFAIK, this requirement is for SQL Server only; if you're running Oracle, you won't see this.
1) Upgrade 7.3.1 to 7.4 on appserver and reporting server
2) Run Data Migration from 7.3.x to 7.4.0 from appserver
3) Upgrade to 7.4.1 on the appserver and reporting server
4) Do the data migration from 7.4.0 to 7.4.1
Contact support to determine if a two-step upgrade is still required.
Second, there was an issue which would throw the following error during migration:
Invalid object name mig_run. SQLState: S0002 ErrorCode: 208
If you get the error above, there's a known solution. I believe the solution has already been integrated in the GA code, so I won't waste space posting it here. It should be a non-issue at the moment.
Last, I ran into an issue where the app server wouldn't start after being upgraded to 7.4.1. This was due to missing entries in config.xml. If you get this error when starting the app server:
+xception in thread "main" java.lang.NullPointerException
There is a known solution. Like the 2nd error, I believe it's already been fixed in the GA code. If not, the solution is to add the AuthSvcPort to config.xml on the application server.
