RE: Re: PVCS to Subversion Migration Problem

We also migrated from PVCS version manager to Subversion.

The whole process on the whole went very smoothly, with the biggest
difficulty being getting used to the change in terminology and the
concepts of working copies.

With direct regards to preserving the modified date times, the design of
subversion means that the modified date times are not as important as
you are able to reference the state of a folder using just the URL and
revision number. In PVCS we used to use the modified date times
primarily as they were a more trusted way of identifying a file. (And
yes you can use MD5 hashes etc. but this is what we USED to do....)

There are still occasions when preserving the modified date time is
useful/essential and these have been discussed on many occasions in the
history on this list and a bug
(http://subversion.tigris.org/issues/show_bug.cgi?id=1256) has been
raised to get this feature added.

Are you using PVCS VM of Dimensions? If you are using VM then I would
definitely recommend moving to subversion as it solves a lot of the
'confidence' problems such as deleting a file will permanently delete
all history.
