Thanks for your reply @Andy+ - I've been using SyncThing primarily previously, but for some things recently I've used Resilio. I followed and I get that the license requirements now needs a business license - but considering the situation where the the VPS provider DOES NOT support any other Windows version but Server...I'm wondering if - for example - I could pay for the current version and then install 2.6.x on the VPS with my current license. It's just to get certain things over. And Resilio is more convenient (easy) with getting things done.
TBH - I may get a license either way for my personal devices, but I use my VPS for a lot of transfers. I live where power/internet outages are frequent - so moving things to the VPS then to my cloud services is better/easier/more reliable. My setup is off-grid so I personally don't need to worry about the outages, but an outage will also mean internet is down. When I'm on the road working I can't hotspot to my home for data transfer. Just as examples.
