Posted on by Mohammed Abdul Aziz 1,875

Experts,

I have only 2 layers, USR and SYS layer in my environment. I have upgraded my test system and duplicated test system to create a dev machine. I am confused, do i need to delete USR ,USP and SYP layer and then upgrade SYS layer?

    No there is no need to upgrade in steps from R2 CU8 to R3 CU9 that I'm aware of, provided you follow the upgrade documentation properly.

    When you upgrade, the R2 SYS and SYP layers should be collapsed into a single SYS layer for you automatically.  If you have any hotfixes installed in R3, then you may have another SYP layer for those, but it will be a different SYP layer and you should not deleted it.

    If you have a USP layer that contains objects, then why did you say you only have a USR layer?  Personally I recommend collapsing your USP changes into USR and keeping the whole thing less complicated.
