Multiple SIM Integrations On Same Tenant

I have a customer migrating from a custom SIM integration to the standard ServiceNow SIM integration, as they are moving from ManagedEngine to SNOW. Will I be able to run multiple SIM integration configurations on the same dev tenant as long as there is no conflict in configured “sources”? Essentially I need to start moving custom JDBC connectors from one SIM to the other while avoiding breaking the system. Hoping to get this clarification before I break current the pipeline of development.
