Important: Do not upgrade your 11.2.4 FP3 content to version 12.0.0 - 12.0.2

[DaBaker]

Good info from IBM:

Important:
Do not upgrade your 11.2.4 FP3 content to version 12.0.0, 12.0.1, or 12.0.2. If you do so, you may need to run specialized scripts before you can do another upgrade to version 12.0.3 or later. If you want to upgrade 11.2.4 FP3 content to version 12.0.x, you must wait until 12.0.3 or later to do so.

You can still upgrade any 11.2.x content other than 11.2.4 FP3 to any version of 12.0.x.
