We are in the (painfull) process of migrating several hundred users from Lotus Notes 5 to eGroupware. It seems there is no “smooth” way for this kind of migration. Most of the emails can be migrated using IMAP to IMAP moving but this particular Lotus release has some serious design flaws, so not all eMails can be migrated so easy. Addresses are converted using a special tool: They are exported from Lotus, converted to CSV and imported to eGW. All other user data (luckily not much) is simply abandoned, it was not so important.
Perhaps a working LDAP setup (on both sides) would have made things easier… I don’t know. We are just adding users in eGW and mail system and then delete the Lotus account and leave an addressbook entry for all users that are not migrated to the new setup.
If you have some hints or questions regarding the Lotus migration, just contact me.
