best way to upgrade

[mike]

the idea of memcache is not a persistent cache... everyone keeps
butting heads with that concept :)

if you're looking for a persistent cache that will use disks to back it up:
http://meta.wikimedia.org/wiki/Tugela_Cache
http://sharedance.pureftpd.org/project/sharedance

however, you should have in your code to hit the database/data store
for the data if it's a cache miss and then update the cache - your
site may be a little bit slow while it's recaching, but that's the
point. it's not a reliable data store, it's a volatile way to save
trips to the database (it's just like RAM (volatile) vs. HD
(non-volatile))
