Import the RAP from 8.4 to 8.8

We are working on upgrading our platform from 8.4 to 8.8 , we are doing an out of place upgrade in POC environment. But until the upgraded code is moved to production the current/ active development happens in 8.4.

So my query is as my active development is 8.4 can I create the RAP and import to 8.8 POC to sync the delta code?

Will Pega automatically upgrade the 8.4 code to be compatible with 8.8?

Or do i need run upgrade utilities or use the Revalidate and Save tool to resave the delta code.

Are there any articles related to this topic?

Thanks in advance,

Suman

I recommend doing a quick smoke test in 8.8 version on the changes implemented/fixed in 8.4 version after each code drop. This is to ensure that new/updated changes are still working in 8.8 version.

To answer your questions:

So my query is as my active development is 8.4 can I create the RAP and import to 8.8 POC to sync the delta code? Yes, that would be my recommendation and do a quick smoke test after each code drop/deployment.

Will Pega automatically upgrade the 8.4 code to be compatible with 8.8? Ideally yes, unless the rules are deprecated in the highest version.

Or do i need run upgrade utilities or use the Revalidate and Save tool to resave the delta code. Not required

@sangr2 Thanks Ramesh. Is there any Pega article which conveys the same?
