We are planning to upgrade CA 2E 8.6 to 8.7 and then 8.7.4. One question we have is if we need to run YDUPAPPOBJ after upgrade to 8.7 or we can wait until upgrade to 8.7.4 then run this command.
CA 2E 8.7.4
You can wait until after upgrade to CA 2E 8.7.4 and then run this command for your library or libraries. That is, you don't have to run this command twice if the intention is to upgrade to 8.7 and then 8.7.4.
