Hi Michael,

My personal view is that when multiple tools are installed in the same
repository, that it is OK to require that they all be upgraded together,
but that you should be able to upgrade different repositories
separately, and have the inter-repository integrations continue to work.
This implies that the intra-repository integrations can assume they
are working at the same tool version-level, but that inter-repository
integrations cannot.

Commonly, even at the cross-repository level, interoperation is only
guaranteed between tools if they are no more than one major version
apart, i.e. a 3.x version repository should be compatible with either a
2.y or 4.z version repository.

Note: To emphasize, the Jazz team has not yet made a commitment in this
area ... what is stated above is my personal view as to what we should
aim for.

Cheers,
Geoff

Hello

How will it be in the future if you have several jazz based tools
installed and you want to upgrade one of them?
Let's say that you have RTC and RQM installed togheter and you need to
upgrade RQM to a newer version.
What kind of impact can we expect to get then, do we need to upgrade
all jazz based tools togheter or is that not needed ?

Regards
Michael
