Zimbra 7.2 Migration To 64bit & Upgrade to 8.0.4 - repost

PLEASE DO NOT RESPOND WITHOUT READING IN FULL, THE LAST GUY DIDN'T AND COMPLETELY SCREWED THIS UP. Looking for someone to migrate a 6 user v7.2 32 bit Zimbra install to 64bit on a new server, and then upgrade to v8.0.2. Good english and experience mandatory, you must have done similar before and be able to do it again. I don't want to be bothered every 5 minutes on Skype unless you need a licence or SSL cert, for example. You also need to be prepared to revert to the old server in case of problems, data loss is absolutely unacceptable. The migration needs to take place on a Friday or Saturday evening GMT. A detailed description on the process is available at the address below, you should follow this guide unless you have a good reason now to. The last guy tried to do it with imapsync FFS!
