SVN - Reintegration Merge error: "must be ancestrally related"

Question

Using TortoiseSVN - when I use Test Merge, I get the error "http://mysvnserver/svn/main/branches/ProjectA must be ancestrally related to http://mysvnserver/svn/main/trunk/ProjectB"

What can I do to resolve this?

Answer 1

I just went through a similar problem, wanted to add the issue and solution I hit. The branch was made from a SUBFOLDER of trunk and not the entire tree. Thus, when I tried to reintegrate, I was mismatching hierarchies. Simply restructuring the integrate to be to the proper subfolder of my trunk WD allowed the process to proceed.

Adding in hopes this might aid someone who hits this Q/A. :)
