I have extended the FAQ entry #dumpload , about the dump+load
procedure, with some caveats and details on the technique to dump+load
a large repository with minimal downtime. This is based on a users@
mail from last year  (I had been meaning to convert this into a FAQ
since then, but only now got around to it). See my edits in r1803274
and r1803323. Questions on how to correctly execute a dump+load
(possibly from a very old repository) still come up regularly on
I have also written a new (related) entry #fix-nonLF-log ,
describing how to fix the "svnadmin: E125005: Cannot accept non-LF
line endings in 'svn:log' property" error one might run into during
'svnadmin load'. See r1803336.
These FAQs more or less cover one of the whiteboard items from the
2015 hackathon  (namely "document ideal procedure for full
dump/load with minimal down-time").
Review, additions, rewriting, ... welcome :-).
Also: this reminds me of those other whiteboard items from 2015:
"svnadmin load --normalize-revprops", "- normalize svn:* props", "-
normalize mergeinfo", to get 'svnadmin load' on par with svnsync
regarding normalization. Having those options (at least the first two)
would make those faq answers a lot shorter ... If anyone has some
cycles to spare, 1.10 might be a good target to try and get these in
