Though I successfully upgraded several other sites, my experience on this site hasn’t been pleasant. Issues I’ve faced (with varying levels of success):
- Upgrade flat out didn’t work, I had to import my exported blog entries (I tried to use a db backup and just had the same problems over again).
- Lost all category assignments (and haven’t found any bulk category assigning mechanism)
- Lost over a year of UTW tags (2.3.1 doesn’t support ultimate tag warrior, it’s got its own internal engine that didn’t accept the old ones)
- URLs didn’t “stick”
- Lost all my blogroll link categorization
