Hi,

You should be able to update from 1.x to 2.x, but it's a bit more complex than the 1.x -> 1.x updates. Try one of these methods:

a) download one of the "Web Install" downloads of RTC 2.0.0.2 and use the update link from the launchpad there (for windows you could get this download: https://jazz.net/downloads/rational-team-concert/releases/2.0.0.2/RTC-Express-Full-2.0.0.2-Win-Web.exe)

b) open your IM preferences and add this repository URL:
https://jazz.net/downloads/rational-team-concert/2.0.0.2/2.0.0.2/install-repository/express/repository.config

(note: Those two links are for Express edition. There are different links for the other editions, but the client is the same in all of them)

I try to migrate clients from 1.0.1 to 2.0.0.2 with pre-installed plug-ins and configuration.
So I tried to use IBM Installation Manager, but IBM Installation Manager doesn't update RTC 1.0.1 to 2.0.0.2 just till RTC 1.0.1.1.

What do i wrong?

Thank you for responsd

I found second way yerstuday by myself just by editing of reposotories psth for RTC 1.0.1 :D
