VPOPMail+Qmail to Cpanel

Hi, I'm migrating mails from VPOPMail+Qmail+RedHat to Cpanel. Source server has this directory format. [root@linux99 Maildir]# ll total 24 drwx------ 2 vpopmail vchkpw 4096 Sep 15 14:02 courierimapkeywords -rw-r--r-- 1 vpopmail vchkpw 47 Sep 15 11:52 courierimapsubscribed -rw-r--r-- 1 vpopmail vchkpw 103 Sep 15 14:02 courierimapuiddb drwx------ 2 vpopmail vchkpw 4096 Sep 15 14:02 cur drwx------ 2 vpopmail vchkpw 4096 Sep 15 14:02 new drwx------ 2 vpopmail vchkpw 4096 Sep 15 14:09 tmp [root@linuxxx Maildir]# cd .. Therefore, I couldn't rsync directly because Cpanel has /home/{user}/mail/{domain}/ directory format. So, I'm planning to rsync each account manually. But to test if I can rsync all mail content, i created a test account that contains one mail for each inbox, sent, drafts, junk and a directory that I created in squirrel I then rsync from source server to my cpanel server. I then fixed permission because the two servers has obviously different users. After fixing the permission though, I can see that only inbox got migrated, but sent, drafts, junk and custom mail folder weren't. I'm still trying to locate where the drafts, sent and custom folder are being saved in the source server but unsuccessful as of this writing. Hope you can help.
