Single SVN dumpfile ONLY?

Guowei Jim Hu (1.0k●9●103●53) | asked Dec 17 '09, 10:55 a.m.
While working on migrating from SVN to RTC using the RTC importer, it seems that it assumes one single dumpfile as input.

In our case, the single dumpfile is over 50GB, too big to move around in the network. So we decided to generate multiple incremental dumpfiles, each for a specific range of revision.

The first dumpfile imported fine. But the subsequent ones can't go through because the Importer wizard won't display the SVN folder structures for select to import. When we saved the folder structure from the first import, and load it up for the subsequent ones, we got an error:

An internal error occurred during: "Import from SVN".
Revision 34593: Missing parent of add at Trunk/src.

Is there a way to around this or we have to use one single SVN dumpfile nomatter how big it is?

Unfortunately, when SVN generates a dump file for a specific range of
revisions, the dumped revisions may still reference revisions outside
that range. This makes it impossible for the RTC importer to import the
data properly.

What you can do is create a single dump file and then use svndumpfilter
to filter out any uneeded subtrees.
