SeaMonkey has built-in tools for migration from various applications, except for those from the Mozilla family. This page will detail how to migrate from those.
IMPORTANT: Always back-up your profile first! A good tool for that task is MozBackup.
It mostly consists of moving files to your SeaMonkey profile. First, learn how to find your profile for both applications. Next, copy the following files from your Firefox profile to your SeaMonkey profile:
- bookmarks.html - your bookmarks
- cookies.txt - your stored cookies
- downloads.rdf - file download history shown in the Download Manager
- history.dat - browsing history
- hostperm.l - per-site preferences for allowing cookies and pop-ups
- key3.db - key used to encrypt and decrypt your passwords
- mimeTypes.rdf - information on what to do with certain files when opened
- signons.txt - list of your user names, passwords, and sites to not save passwords for
If you don't have a file in your SeaMonkey profile that looks like (number).s, launch SeaMonkey and make it save a password. When you have the file, remember its name, delete the file, and rename signons.txt to that name. Because of incompatibilities, your browser settings can not be copied. You'll have to recreate them in SeaMonkey.
It consists of moving files to your SeaMonkey profile, and then recreating your account(s). First, learn how to find your profile for both applications. Next, recreate your accounts in SeaMonkey Mail. Then, copy the following files/folders from your Thunderbird profile to your SeaMonkey profile:
- abook.mab - your Personal Address Book
- history.mab - your addresses
- mailviews.dat - message view definitions
- msgFilterRules.dat - message filters
- popstate.dat - stores which messages have been downloaded by POP
- training.dat - Junk Mail Controls training data
- Mail - folder containing all your e-mail
- News - folder containing all your news messages
If you haven't already made SeaMonkey save passwords, you copy the file key3.db and a file that looks like (number).s over as well. Because of incompatibilities, your mail settings can not be copied. You'll have to recreate them in SeaMonkey.
