License Transfer

Hi,
I need instructions how to transfer step by step the license from the design computer to company server. So here is the case:
Ignition version 8.04., connected to Kepserver 6.8, SQL Server Express 2014; gateway, project and tags backups done.
Shall I install the latest Ignition gateway software version (8.08?) to the server, or I have to install the designer PC version - 8.04?
Is it possible to dis attach SQL Express table and attached it to SQL Server?

Up to you. Have you tested the differences in a sandbox?

Yes.

Thank you for the prompt reply.
So, after licensing the new gateway, just import the project and the tags?
Regarding the sandbox test, differences not tested. Let me first learn more for that sandbox.

GWBK would be preferred over single .proj export.
