Yes, I'd expect v3 pools to go stay the same or down if anything but they are increasing in size. And the pool files (either v3 or v4) should not grow anyway- all active hosts are set for compression.
The documentation has these bits which are relevant "V3 migration: nothing specific is needed. V4 can browse/view/restore V3 backups. "When a V4 backup is first done, BackupPC_backupDuplicate is run to duplicate the most recent V3 backup to create a new V4 backup. A "filled" view of the most recent V3 backup is used to create a "filled" V4 backup tree. This step could be time consuming, since every file needs to be read (as a V3 file) and written as a V4 file. However, the V4 pooling code knows about the V3 pool, so it will move the V3 pool file into the V4 pool. So this duplication process doesn't burn a lot of pool storage space, but every file still needs to be read (to compute the MD5 digest) and "written" (really just matching/linking)."
