Re: StarTeam to Subversion migration

StarTeam does version each individual file like CVS, RCS, SCCS, and
ClearCase, but the command line interface didn't allow you to specify
a particular version of a single file like you can with these other
version control systems. With these other systems, you can easily pull
out a version tree of an individual file, and then proceed down the
entire tree, checking in and out every single version of the file.
There isn't anyway of automating this with StarTeam.

The command line interface is poorly documented and almost impossible
to use without a lot of automation. It isn't uncommon to have to type
60, 70, or more characters for a single StarTeam command (especially
since each command must contain the full authorization string in it).

We simply decided to import only the current version, and what was
actually out in the field into ClearCase. I think this ended up being
four, maybe five different versions. We kept StarTeam around for a
while, but I don't believe we ever went back to the StarTeam source to
look something up.

BTW, "svn_load_dirs.pl" does sound an awful lot like citree, which
would save you some time and effort.

The best solution is simply to manually checkout each version you
want, then run "svn_load_dirs.pl" on it. Do this for each of the
"interesting" versions in StarTeam, then keep StarTeam for a couple of
years until everyone feels that the history in it is no longer needed.
