Does anyone have any recommendations for someone to manage the migration of several websites and email accounts from one host to another?

Anyone who runs a web design business should be able to look at that...
biggest issues will come if the servers are setup differently and therefore code stops working...
It is boring work esp. if you need full testing, and depending on the complexity of the code can be quite a lengthy job...
simple brochure websites - probably few issues, complex process based systems, could take a lot of time...

as an example, we have been moving sites from one of our servers to another, in order to decommission an older server - simple brochure sites are generally - check you have a copy of the code / content, set up new site, upload - check permissions on folders - live. Our most complex site, we are 4 months in and not there yet as the system has to also talk to the client's servers and internal systems, and there are discrepancies even between two servers we control, nearly done now, but it has meant substantial change in places...

email, can be a simple or complex job depending on what you need - are you happy to archive the current mailbox on your computer and set up a new one from here onwards, or do you need full mail migration? Can also depend on the software you use to read the email...

Thanks for your reply.

I don’t think the code will be an issue, as all the processes are done on e-commerce servers elsewhere and the code moving is pretty simple.

For the emails, archive would need to move too, so will be lumpy.

For me, it is the seamless migration that is important - we can’t have downtime on either.

How are you going to manage the DNS change ?

I can introduce you to a guy who specialises in exactly this. Nothing to do with me, just a guy I know who can do it.

Exactly why I need someone who knows what they are doing!

Take a backup of the websites and upload to new provider and perform UAT, then switch the DNS over to put the new sites live once you are happy. As the above poster noted you will need to make sure your webdev hasn't hardcoded any paths into the site contents as this could lead to considerable work to find and fix

Email migration is as simple as redirecting DNS records to the new mail system. If there is existing mail in an archive Im assuming it can remain in place client side and new emails will just continue to come in via the new server. If the mails are archived on the existing hosting server then they will need to be downloaded and reuploaded again into whatever database or format they were held in

Thanks...I understand the theory, but I’m no tech guy and whilst I could take the risk on my own businesses and their basic email and website needs, my wife’s e-commerce business is now pretty big and employs a few people and it would be rather embarrassing if they ended up sitting around doing nothing because I missed something!

and during DNS propagation?

Nobody mentioned a DNS migration. Just change the TTL of the individual records to ~ 5 mins temporarily

We can do this and often do for clients, although following a chat we may turn it down as this type of job can be a nightmare.....

Some valid points raised on DNS propagation that would need to be considered.

Which host to which new host?

How many IMAP accounts?

PM me to discuss further buddy

DNS propagation is only valid if you are changing nameservers, not individual A / CNAME or MX records

But DNS caching does hence why you want to set up a v low TTL a few days ahead of time.

Also make sure you look at the analytics (both of sales as well as traffic) and look for weekly or monthly patterns to ensure the move is done as the absolute low.

This ^^^ Correct timing is always important when migrating. We do a lot overnight
