Magento server migration

I need to move a Magento 1.x site to a new server. The process will happen over the month of November. Specifically I need the following:

- A list of requirements to send to the current website developers so that we can arrange for an efficient handover of the current code and data.
- Once we have received the necessary information I'll need the site setup on a new server (we can build the server to your requirements and ssh access will be provided) and fully tested.
- We'll need help managing the release so that no data is lost and so that down time is minimised.

The Magento site currently integrates with EposNow, and we'll need to make sure that the integration continues to work after the migration.

I am looking for a Magento specialist. If I find the right person, we may ask them to update the site to Magento 2 in early 2020.

Many thanks

Stuart
