Rational ClearQuest clients must be at version 7.0.1 to connect
to user databases with feature level 6. These clients includes the administrative
tools such as the Designer and the Maintenance Tool, as well as scripts and
end user clients.
However, Rational ClearQuest clients running version 7.0.1 or higher are
backward compatible and can connect to user databases with feature level 5.
Rational ClearQuest clients running version 7.0.0.0 or earlier cannot connect
to user databases with feature level 6 enabled.
In a Rational ClearQuest MultiSite environment, databases on feature level
6 can read packets sent from databases on feature level 5, but databases on
feature level 5 cannot read packets sent from databases on feature level 6.
You have the following choices:
- If all databases must accept packets from all other databases in the Rational
ClearQuest MultiSite environment, then all databases must be
upgraded to feature level 6 at the same time.
- If some databases do not need to accept packets from the upgraded databases,
then the former can remain on feature level 5 and be upgraded later.
