Server 1.9.3 (Windows) and client 1.8.15(Linux-Centos6.5) We are in the mist of refactoring our directory structure from the monolithic (Clearcase imported) directory structure to moving subdirectories to new repositories and using svn:externals with pegged versions back into the primary product repository. No big deal but my user base is complaining about two big problems: tree conflicts and merging issue: "svn: E195020: Cannot merge into mixed-revision working copy [8:9775]; try updating first" but running "svn update" will not solved the problem. I want this conversation to just discussion the process of converting a directory to use svn:externals. I'll start another topic on the mixed revision issue. The problem I have is these subdirectories have build artifacts in them so when a "svn delete" is performed, the subdirectory remains. So whether a single update where the "svn delete" and the new svn:externals are defined or it is broken up into two updates, I get tree conflicts. I assuming I'm answering my own question here but I believe I need the two updates and I send out instructions to my user base to update to the 1st revision, manually the local subdirectories and then update to the 2nd revision. Anyone see a way to simplify this? ---- Brent
