Unfortunately my experience has been different.
Pickaweb did my migration last Friday (a week ago).
The time interval between the email saying they had started the migration
and the one saying they had finished was only 3 minutes.
Fortunately my DNS is hosted elsewhere, so all my services are still
running at Gradwell ...
I think Pickaweb have probably migrated the email setup and email
forwarding correctly (though I've not yet dared to switch my MX record to
point at them).
They had not migrated any of my mySQL databases. They did migrate them
after I raised that question in a reply to the migration ticket. But they
said they were unable to find out what other mySQL users I had in the
databases at Gradwell, so I've had to reconstruct those myself.
They had attempted to migrate some (but not all) of my various web-sites
files, but some of those had been migrated to the wrong level in the
directory hierarchy.
They had made no attempt to migrate any of the other files in my Gradwell
developer account (I think that was the term Gradwell used when I opened
the account many years ago), and in response to my asking about this they
asked if I wanted them to migrate the contents of my home directory at
Gradwell to the public_html directory at Pickaweb - no thank you!
I've spent most of today copying files to Pickaweb and getting the
structure correct for the files they had copied.
My experience of the Technical Support has been very different to yours -
I've engaged with them through their ticketing system (replies take
several hours, and they don't seem to be reading what I write) and via
live chat - this evening a 25 minute pause in their advisor replying part-
way through the conversation and then saying "Sorry we are facing a large
qeue of chats, we will check and let you know through the ticket"
At the moment, I'd rate their Technical Support as marginally better than
Gradwell's - a few hours to reply is better than days or weeks, but I
don't find them knowledgeable.
