How to migrate from PRINC to PR_SERVER?

How to migrate from PRINC to PR_SERVER?

[Mike Looijmans]

Attempting to move to the current OE-head now yields about a hundred 
messages like this:

WARNING: Use of PRINC 7 was detected in the recipe ...

The https://wiki.yoctoproject.org/wiki/PR_Service page tells what the PR 
server is.

However, it does not tell what to do with the recipes. Just removing 
PRINC from the recipes will break the upgrade path.

What are we supposed to do now?

PR_Service doesn't help with PRINC removal, because PRINC is applied on
first number in PR and AUTOPR is appended as extra number after dot.

You were supposed to send corresponding PR bumps to upper layers when
removing PRINCs, like:
http://git.openembedded.org/openembedded-core/commit?id=c6825ec6e92e20bb64a051d1576f363c16e98d68

but it's probably too late for daisy.

You can wait for PV/PE upgrades in upper layers or in worse case break
upgrade path and remove PRINCs without replacement (e.g. if it's in your
private layer and company doesn't care about upgrade path).

So what is the relation then? Why is PRINC now suddenly declared 
obsolete, without providing anything to replace it?

That would also mean hand-crafting several dozen of PR numbers. And for 
a project like OpenPLi for which there are something like a million 
embedded boxes running and upgrading it in the field, I'd definitely 
want to keep the upgrade path clean...

Would a patch that bumps PRs for so many packages be accepted?
