[Pulp-dev] Pulp 2 and 3 Service Name Clashes

[Brian Herring]

Is one of our goals is to move all possible resources to working on Pulp3?

If so, I am going to agree with Kersom on the basis that it seems strange
to make changes to a product we are attempting to sunset and should be
making minimal changes.

Do we know all the impacts that changing service names in Pulp2 would have
on Pulp2 yet? If we have and are still making changes to Pulp3, doesn't it
make more sense to make those changes there when the product has yet to be
launched?
