I don't think so:

http://docs.oracle.com/cd/E17076_02/html/installation/changelog_5_3.html#idp50933456
http://docs.oracle.com/cd/E17076_03/html/installation/changelog_5_2.html#idp51156152

Just the log file format, eg. it needs some care, in case you use the
journal, you can adapt my script from cyrus-imapd-2.4:

http://anonscm.debian.org/gitweb/?p=pkg-cyrus-imapd/cyrus-imapd-2.4.git;a=blob;f=debian/cyrus-upgrade-db;h=866053c2a358147ea9d46d82f1896f3d3cd91cab;hb=HEAD

you need parts of backupdb, upgradebdb and checkpointbdb, but
cyrus-imapd uses berkeley db transactional environment, so it's more
complicated.

or here's a more generic upstream guide to upgrading:

http://docs.oracle.com/cd/E17076_02/html/upgrading/upgrade_process.html

Generally backing up the files and calling db5.3_upgrade should be
enough for most simple cases.

Feel free to ping me again, if you need help. Hopefully this will be the
last upgrade we will ever make.
