February 23, 20251 yr I currently have 1 parity + 8 sata drives and 2 cache drives all connected to my current mobo. Which has a ton of sata ports. The mobo I'm looking to upgrade to only has 8 sata ports so I will need to use an expansion card to get everything connected. Some will be plugged into the new mobo and the rest on the expansion card Adaptec ASR-7805 SAS2 HBA. Will Unraid just find all of my drives and have my array available when I boot up for the first time on the new hardware or will I need to reassign all the drives in the correct order? As I understand it, I will just use my current Unraid USB stick and boot the new system with that and everything connected. Also. My current system is using ECC ram and the new system will not be. Does that matter at all so that my array works on the new hardware?
