Merge from one branch's working copy to another branch (locally, w/o committing)

Question

Most of my experience is with Perforce and my last svn experiences were ages ago, so I'm not yet that comfortable with (Tortoise) svn (again).

I want to move changes over from a working copy to a freshly checked out working copy in another related branch.

To be preceise, consider:

    trunk_revx
        |     \
        |      Branch_A
    trunk_revy   \
        |\       WC_A (containing my changes)
        | \
        |  Branch_B
        |    \
        |    WC_B (fresh, where I want to merge my changes to)

Which would be the correct command to get me a three-way-merge between WC_A, trunk_revx and WC_B without committing anything? Merge (call in which WC folder?) or Switch (again, call where?)?

All the terms are different, So I'm a little lost ;)

Answer 1

I suggest you the following actions:

1. From WC_A: save your local changes by creating a patch file with TortoiseSVN (in case the next actions would fail and lose your changes)
2. From WC_A: perform TortoiseSVN ==> switch... and switch to Branch_B:
   • the Branch_B is merged into WC_A (locally)
   • and your local modifications are kept
   • and now your WC_A points to Branch B

You just have to deal with the fact that your WC_A becomes your WC_B !

Alternatively, if you don't want to commit into Branch_A, but can commit anyway, you could also commit local changes to a new small branch (a branch of branch_A) and perform a merge from this new branch to Branch_B.
