Implementing ARP from FSM

Hi,

Historically we have had FSM and PSO and all data initialised into PSO each day for scheduling.
FSM has always been the master for the data in terms of Rosters, Shifts, Resources, Calendar Exceptions etc.

Our Resource Planning Team work 100% in FSM. This does give us some restrictions.

I started to look at ARP in PSO (early 2020) and could see straight-away this would give us some massive benefits to how we operate and manage resources. 
Unfortunately some pandemic came along and objectives / priorities were changed. However this is something I want to revisit.

I am therefore asking the community if any customers have made the jump from FSM nightly 'INITs' to ARP for managing resources?
If so is there anything that can be shared in terms of steps to setting up ARP.
Things like migrating current work calendar's and rosters reducing set-up time for cutover.
How to manage updates in ARP i.e. calendar exceptions, shift data, and feed that back into FSM. We have our dispatch teams working solely in FSM too, so anything changing in ARP would need to be replicated back to FSM.

I know ARP will give us massive benefits in terms of flexibility to manage resources, but along with setting it up and going live, what other things do we need to look out for.

Happy to share more information / have discussions if anyone has been through that process.

Alternatively if any Consultants have completed the same process with customers and can offer any advice that would be lovely.

Best Regards

Ady
