Merge 2 Unrelated Branches in Bazaar
To merge 2 entirely unrelated branches or projects, we need to specify 0 as first revision in revision range. Turn on terminal (in Mac) or cmd (in Windows) and get to your project folder. Merge with the following shell script.
merge -r0..-1 means to merge from revision 0 to the latest revision.
bzr merge [other_branch_location] -r0..-1
