[MlMt] Moving ISP/IMAP host

[Gavan Schneider]

Greetings, community wisdom needed

Context:
Two domain names hosted by separate providers
I have full control over the DNS routing for these domains (ie., the domain names were not purchased through the ISP providers)
One of the providers has twice blocking my IP address, and once disconnected me when they failed to do their upgrade properly. The other has caused no problems over the same period.
The problematic ISP has taken days to resolve the issue on each occasion… with loss of email access, etc.
I have all the email on local store

Plan:
Put all my “eggs” in what appears to be the much better basket

Proposed process, and your thoughts and wisdom welcome here —
1. Take IMAP accounts “off-line”in MlMt
2. Switch DNS of the relevant domain name to the good provider
4. Create the email accounts on this provider
5. Change the IMAP account settings in MlMt
6. Wait for the DNS change to propagate
7. Bring accounts “on-line” in MlMt… and
8. Allow the synchronisation process to happen, with lots of messages getting loaded on the ISP server (I hope)
9. Clean-up in account maintenance mode on bad provider once I get access again (find any missing messages, etc.)

I have the bandwidth to cover this and speed is good so it should all happen in reasonable time provided I am correct in my process.

So, have I made any silly assumptions or omissions in the above?

Thanks in advance
