I am trying to migrate from Openwebmail to Zimbra. I have tried a few scripts and found one that worked in testing. However, now that I have tested migrating all 250 users, I have since deleted the users who are not going live at the moment. During the initial testing, I was able to migrate 2 accounts successfully several times each time overwriting the folders with no duplicates. Now that I have migrated and deleted all 250 users I get duplicate, triplicate and sometimes sextuplicate of each e-mail being migrated. I am live with about 7 users now and some of them have even reported their contacts were duplicated as well. This all happened after I did the full migration and set the catchall.
My legacy server accepts all e-mails and there is a forward setup to go to an alias on the Zimbra server. Everything else has been working pretty good for the past 2 - 3 weeks. I can't migrate other users until I fix the duplicate etc entries. Could the catchall or the fact that I ran the migration test several times to work the bugs out be causing this issue? Perhaps I didn't delete the users correctly (i used the admin console to delete all of the users).
I used the owm2zcs script from
Mail Migration - Zimbra :: Wiki
after creating all of the users from the passwd file.
Release 7.1.1_GA_3196.RHEL5_64_20110527011124 CentOS5_64 FOSS edition.
Not sure what information would be helpful since i am not getting any errors.
Thanks
