How can I branch "main" node of a UCM project?

Question

We're using RAD with ClearCase plugin as "ClearCase Explorer Perspective". I need to make a new main version of a java project. For that reason, I want to change main/0 version to ie. main/1. How can I forward version from top-level? I tried to make new project by using "Project Explorer" creating new stream. It required previous baselines. However, when I checkin from this new project stream, it branches from the given baseline version(say 1) like below.

main
|
0
|
MyProj1_Integration
|
0
|
1(BL)---MyProj2_Integration
|          |
2          0
           |
           1

I want it to be like:

main
0  ------------------- 1 
|                      |
MyProj1_Integration   MyProj2_Integration
|                      |
0                      0
|                      |
1(BL                   1
|
2

When inspecting versions from ClearCase Explorer version numbers are shown like below:

/main/MyProj1_Integration/MyProj2_Integration/1

I expect to see:

/main/MyProj2_Integration/1

Also, I want to include latest versions of files from previous branch to the new branch. How can I achieve that? Do I need to create a new VOB?

Answer 1

/main/0 is only accessible from the 'INITIAL' baseline.

That means you need to have on your MyProj2_Integration an baseline ending with _INITIAL.
Only that foundation baseline will branch from /main/0.

Once you have that configuration, you will then be able to make a 'deliver' from 'MyProj1_Integration' to 'MyProj2_Integration', in order to get back the latest versions of your first project in the new branch 'MyProj2_Integration'.
