lightroom 3 license switch from mac to pc

I am assuming that the path to the master files will change, however much I try & keep the naming the same, so key question. I have no idea if the RAID system will automatically work with the PC, or whether it will have to be reset & reformatted. I will install a Windows 10 PC next week & my intention is to simply copy the LR catalogue to the internal hard disk on the PC & plug in the external RAID to the thunderbolt port on the PC motherboard.

I would want to access and update the catalog in LR for the MAC and PC whenever I happen to be using that particular machine but they will never be run at the same time.

(I have played with editing, but it is still far too restrictive.) recent convert to MAC but still use PC as well and was wondering if I can open and use the LR catalog that exists on a shared drive between the 2 machines (not at the same time). I sync my entire library to the cloud, which I use on mobile devices for reference. It may be in the future that I trust Adobe to store & manage my master files, but not yet. I currently use an iMac where the LR Catalogue is on the internal disk & all the master image files are stored in an external RAID system (thunderbolt). My question is, how to I best prepare to move my entire system.

This is because there are simply too many unexplained performance issues.
