No obviuos problems me thinks.
Just a tip to add: If indeed you will be cleaning out the 500gb SDD, do a small test first: before adding the new disk, try and boot the system without the 500GB SSD connected and see whether it will start. From what I've seen, the UEFI technique could be using the 500GB for booting. Even if it does not state so in BIOS.(I've done some disk upgrades, all looking fine and good, then remove/format the old disk, and see windows unable to boot. Not a nice thing to experience - You think you are all done and set and ready, and next .... )
And be careful, should you need to some disk-management / partitioning, and that 2TB backup disk is still in the system... make sure it has a clear and meaningful Volume Label - I've seen backup disks/partitions being cleaned up by mistake, just because once windows was in 'trouble' and it needed some repair procedure, it had changed drive letter assignments so like what previously was drive E:, suddenly shows up as D:, the drive you thought you needed to clean up Mind you, just all pre-cautionary tips this... Should anything go differently than planned - it can all go very wrong very fast while trying to repair stuff!
