Logger Peering (Software Logger AND Appliance Logger)

Dear Experts,

I hope all is well.

Kindly, I need to build a pool of logger (One Search head and Two Data nodes). Also,  I have an appliance logger which has already data almost one year.

Q:- Can we install a search head and one data node as software logger(Ver 7.3.0) with the latest version and do peering with the appliance logger(ver 7.0.0)?

Q:- Should we rebuild the new data node with the same receivers, devices, and storage groups as the old data node?

Thanks In Advance
