JDE Apps 9.1 Tools 9:1.4 to Tools 9.2.4 upgrade

I am looking to do a tools only upgrade for JDE 9.1 apps to 9.2 tools (9.1.4->9.2.4) the install is on an IBM i (7.2), and uses Weblogic.

I will be going to Windows 2012 for weblogic (just create new web servers, I don't see any issue here).

Does anyone know of any 'gotchas' in this tools upgrade.

Normally tools upgrades are pretty innocuous, but I just want to make sure.
