Migrating Project Server 2016 configuration without data

Hello,

We are running Project Server 2016 environment (on-premises). We have 1 single server environment which we use for development and testing. However we need to migrate this to the following:

1. 1 single server environment but the configuration only without any project i.e. transfer of Enterprise Calendars, Enterprise Custom Fields, Workflow Stages, PDPs, EPTs, Project Server workflows etc. only
   
2. 2 server environment i.e. 1 Application and 1 Database. This also needs only configuration to be transferred and not the data.

How shall we achieve the above mentioned requirements?

Moreover we also need guidance (steps) to migrate from development to staging and from staging to production clean.

Regards
