Recreate server from backup

Hello – Can someone please provide be step by step guidance on recreating a production install on a new server? Specifically, I am unsure of the following:

1. What should be backed up on a production server – database is obvious, but I am sure there must be other files/folders that need to be backed up (where are uploaded images and attachments in the application stored?).
2. My production server has some Entity updates (done using System->Entities->Entity Management) like new Entities and new Entity Fields. What is required to move them correctly to the new server?
3. Should any extensions/customisations (like new storefront UI theme bundle) be simply reinstalled? or is there a better way of backing these up and restoring them on the new server?

Below is what I have tried:
1. Installed application fresh on the new server.
2. Stopped cron tasks and running consumers
3. Restored the database
4. Tried clearing the cache – that’s when I started getting errors (for example,
In MappingException.php line 772: The target-entity Extend\Entity\EV_Customer_Customer_Type_Fe542000 cannot be found in ‘Oro\Bundle\CustomerBundle\Entity\Customer#customer_type’.)

Many thanks for your help!

Hi, Peeush.

Reinstall is not an option when you move the website to another server.

Please follow the below steps:
1) Copy all the source code from an old server to the new one, except var/cache and var/logs folders. Or when you prefer to install from SVC, copy Assets in var/attachments and public folder and artifacts in var/import_export folder, they are required.
2) Change credentials at the config/parameters.yml file for the database and optionally to other used services (ElasticSearch, RabbitMq, Redis etc).
3) Copy the database
4) Follow the upgrade guide from step #7 (or step #6 if you haven’t copied all the vendors from the previous server). This will warm up all the required caches and so on.

Thank you for guiding me in the right direction Andrey! I will try out the steps you have outlined and will reach out if I am still running into issues.
