TO BE CONTINUED.
Please try it on a test server first, if it works well, then try it on product server.
Since new iRedMail server will install same components as old server, you can choose what data you want to migrate. The major data are mail accounts, roundcube webmail database, mailboxes.
LDAP: migrate mail accounts
Steps to migrate LDAP mail accounts:
- Setup a new server with the latest iRedMail, and make iRedAdmin-Pro-LDAP work as expected.
- Export mail accounts from LDAP on OLD mail server.
Normally, LDAP data can be exported into LDIF format. Here's backup/export script: http://www.iredmail.org/wiki/index.php?title=IRedMail/FAQ/Backup
After exported from old server, you will get a plain text file which has LDIF data. You should remove top some items, includes:
- dc=xxx,dc=xxx
- cn=vmail,dc=xxx,dc=xxx
- cn=vmailadmin,dc=xxx,dc=xxx
- o=domains,dc=xxx,dc=xxx
Because we will use these ldap objects on new server, so remove them from exported data.
Assume the exported backup data is saved in file /root/old.ldif
- Now, log into phpLDAPadmin with cn=Manager,dc=xxx,dc=xxx on NEW server, remove object of your mail domain. it should be:
- domainName=your_domain.com,o=domains,dc=xxx,dc=xxx
- Remove all sub-objects under this object.
- Import /root/old.ldif with phpLDAPadmin.
You can find a button named "Import" in phpLDAPadmin left panel.
- There might be some changes to LDAP schema, please read all upgrade tutorials for your running iRedMail version, then apply LDAP data related upgradings. For example:
Note: You can find all upgrade tutorials here: http://www.iredmail.org/doc.html#upgrade_tutorial
MySQL: Migrate mail accounts
Migrate mailboxes (in maildir format)
- Simply copy all mailboxes (in maildir format) to new iRedMail server.
WARNING: please make sure maildir path which stored/configured in LDAP will match the real path on file system, so that mail clients can find them.
