Problem migrating repo from windows to linux
I started with an svn repo on a windows box, and now I'm trying to migrate
it to a linux box.
I did your standard dump on the windows box:
svnadmin dump /path/to/repo > reponame.dump
Then I moved it to the linux box and ran:
svnadmin load /path/to/repo ~/reponame.dump
And I got this error:
svnadmin: Malformed dumpfile header
I've searched around and the only lead I have is that it has to do with how
windows handles newlines compared to linux. Any ideas on fixing it?
Thanks

The problem is that svnadmin load expects the dumpfile on STDIN.
you want
svnadmin load /path/to/repo < ~/reponame.dump

Hi Subversion Gurus,
Any thoughts/feedback on moving FSFS Repository across OS by
zipping/tarring the repository and unzipping/untarring on the new OS.
Are there any technical reasons why this should not be done as described
by Talden below.
I have done the above from Linux to Windows and did not experience any
issues. Your clarification on this issue is greatly appreciated.
This process assumes there is no activity on the repository during the
move.
Thanks
Lakshman

My understanding was that textual diffs were EOL normalised to be server
native. This would break when copying a repo between platforms wouldn't
it?
In addition I thought I heard mention of an architecture dependency as
well (I'm assuming endian-ness and possibly word-width) but this may
have been only BDB.
If this isn't the case then it makes FSFS even more compelling.

Hi Derek,
If your repository is on FSFS and you can ensure there will be no
activity during the migration process, then I believe you could zip the
repository and unzip it on the Linux server.
Thanks
Lakshman

I actually figured it out. The issue was
svnadmin load /path/to/repo /path/to/backup
should be
svnadmin load /path/to/repo < /path/to/backup
doh! The tutorial I was reading left that important part out.

The dumpfile format should make that a non-issue.
Is it possible the file just got corrupted when transferring it
between the systems? Have you tried creating a new dumpfile from
the
Windows box & loading that into the Linux-hosted repository? How
about
loading the dumpfile into another repository on the Windows box?
You did run svnadmin create /path/to/repo before attempting the
load, right?
