3.0.1 client to 4.0.3 server

Kim Soederhamn (1.5k24348) | asked Nov 08 '13, 9:41 a.m.
Hi we are upgrading a server from 3.0.1 to 4.0.3. They client however will stay on 3.0.1 for a while.
Now when all the users start using their client after the upgrade will they then run into problems using the existing workspace and repository connection or can they just reuse it as if nothing had happened ?
(The server does not change uri its just being upgraded)

they will continue to work fine.   of course they won't get any of the newer features or client fixes.

An RTC 3.0.1 eclipse client will continue to work with a server that has been upgraded to 4.0.3.  Once you choose to upgrade the eclipse client to 4.0.3, you can still reuse your existing workspace. Thus, you will not need to create a new workspace and will not need to recreate repository connections.

Hi Rosa,

I'm not sure this is fully the case. Multiple users have seen that they are not able to expand their project areas (they click the twistie but nothing happens) after the upgrade. Disconnecting and connecting seems to solve the problem at least for now.
expand not possible

in the .log from the workspace .metadata I find this problem all over:

So to me it seems there is a problem with the keystore finding certificates after the server was upgraded(to be fair its also located on a new server´with the same dns name)

Kim the keystore messages can be ignored. RTC uses it's own keystore
As for the other issue you might want to test a 4.x client. Just because it is supported doesn't necessarily mean there won't be any issues.
If it works ok with the 4.x client you may want to open a defect or a PMR
