Currently our company is running out of space on the mail server. I am running Release 5.0.2_GA_1975.RHEL5_20080130212656 CentOS5 NETWORK edition for the server. The server is currently configured as a mirror and I purchased 2 new bigger drives that I would like to replace the existing ones with. Without losing any email at all in the process how or what are the proper steps in carrying this out? My question is purely in the process and not on how to do the mirror config or anything of that sort. I can't figure out how to possibly backup the data, place on the new mirror, and somehow not lose valuable email time to this whole process. Any help is appreciated. Are there any magic utilites provided by Zimbra for this process? Surely I am not the only admin whose had to migrate there email server to bigger drives, whats the magic bullet?
