Migrating from IDPA 4400 to another IDPA 4400

I think the major concern is with migrating DATA, and a good solution is provided below.

As for JOBS (I assume you refer to Avamar Backup jobs),  you should be using Backup Policies (includes: schedule, retention, members, data set), which should be relatively few- and easy to recreate. 

For migrating DATA, I suggest standard Data Domain REPLICATION.

Below is info about Replication:

With IDPA, only meta data is stored in Avamar and customer data is stored in Data Domain.

There is some replication already setup between Av and DD, but when customers speak of replication, they usually refer to customer data between DD systems, usually at different sites to provide DR.

Below is a good place to start as it describes the replication architecture options (Ch 4), as well as CDR (Ch 5) and Cloud Tier (Ch 6). 

It is not specific to IDPA, but IDPA is essentially a hyper-converged AV/DD solution with extra tool thrown in, so Avamar and Data Domain references generally apply to IDPA as well. 

This is an example but you should search Dell Support for your version.
