I have two user partitions (not counting any hidden/system ones like Lion Restore etc.) on my MacBook Pro's internal HDD: Volume_A (100 GB) and Volume_B (20 GB). My Time Capsule has been keeping everything backed up nicely for a little over a year now.
I now want to re-partition my volumes (no change in names). Volume_A: 100 -> 70 GB and Volume_B: 20 -> 50 GB.
Since I also have access to a CCC backup of both partitions, I can easily delete Volume_B, recreate it with the new, increased size and restore the data into it from the CCC backup.
My question is: will Time Machine/Capsule be able to retain the history after the new partition scheme goes live? Or will it decide to wipe the slate clean and start with a fresh backup of the newly re-partitioned setup?
Is there any way to make sure I don't lose my history and have backups "continue" and build upon the existing collection?

Okay, so it looks like there is no need to worry about losing backup history on the time-capsule as long as the names of the volumes are unchanged.
Since there were no answers here, I just bit the bullet and went ahead with what I had originally intended to do. Fortunately, TC picked up the deltas after I resized and restored the data into Volume_B.
So now you might be wondering why I even bothered to ask in the first place. Well, the reason I was concerned is because the first time around, when I went from a single partition layout (backed up on TC) to a dual partition layout (with the name of the first partition unchanged), TC had somehow decided that it needed to start from a clean slate, and I lost all the history there.
