Running really old version [1.23]...will I have any problems updating to current?

texasnightowl · 08-04-2016, 07:24 PM

I haven't been here on mobileread for a while and haven't been updating Calibre either.

I am currently still on 1.23 and I see the current is 2.63.

Will I have any problems updating Calibre? That is quite a few jumps in releases. (94 if my math is right!)

I do plan to back my Calibre libraries up before I upgrade.

Any other advice?

Backup the database file in the Calibre folder (I'm not at home, so I don't remember the exact name - maybe "metadata.db"?). I know at least a couple of the Calibre updates changed the database structure and couldn't be automatically rolled back. So if you thought you might want to rollback to an older version, keeping a copy of that database is a safe practice.

Also, What operating system are you on? I believe WinXP folks have to stop at 2.0 or thereabouts, or risk it stop working. If you use WinXP, you might want to search in the Calibre forum.

Thanks for the input! I was on Win 7 and just upgraded a couple days ago to 10. So I'm guessing I should be OK.

XP is limited to 1.48 (the last 1.x) (the 2.x installer will stop you from doing this on XP)

You must have a SSE2 compatible processor (not an old AMD Athelon)
