Nice Simon, happy for you!
Current work place I work for is almost the opposite, mostly on prem DCs, but we use cloud for backups and o365 that about it.
First place I worked royally f**ked their pays up, it was a call center so some weekend work needed at 1.5x rate, but if you took a sick day or annual leave day in the 2 week pay period as well as work a weekend day their system would get all f**ked up and they paid about $400 extra for the fortnight (over the top of the weekend rates)
At EOFY with the group certificates I was worried they'd figure it out and have to pay what I wasn't entitled to back, but they didn't.
If I did it every fortnight would of equated to about a approx 30% pay rise I reckon lel
