Repairing an HA failover pair

[CAR IT]

We had a 5510 fail in our HA active/active failover pair. I've rebuilt the failed one by replacing the internal CF and reloaded it to the point it's ready to be paired. My question is, I could only find a 64MB CF, and the original one was 256MB. Aside from the obvious disparity (which I'm planning on ordering a 256...) will the paring be rejected if they aren't exactly the same, or will it allow them to be paired.

I didn't immediately order a used CF because we're buying a couple of new 5516s, but now it looks like that process will take a while. Sorry for posting a similar question, I had asked one a few days ago related to this, about licensing.

Thanks!

As per cisco best practice for HA cluster.

If you are using units with different flash memory sizes in your Failover configuration, make sure the unit
with the smaller flash memory has enough space to accommodate the software image files and the configuration
files. If it does not, configuration synchronization from the unit with the larger flash memory to the unit with
the smaller flash memory will fail.
