You should perform a checkpoint before the recover, but otherwise,
it's fine.

4.3 has a bug which causes it to choke on old-format log files when
DB_RECOVER is also specified. This means that my favorite
instructions won't work. Invoking any 4.3 application that opens the
environment with DB_CREATE (but without DB_RECOVER) and writes
something to the log should fix things. Maybe some svnadmin command
can achieve that?
