I did this, I get this output, I guess this means pools are used, hence no issues should occur.

# I must ascertain if it is financially feasible to buy the controllers to perform this upgrade.
Since virtual pools are in use and we are not changing protocols, we are keeping iSCSI, on first glance it seems possible that we should be able to simply power down, remove disks, put in the new controllers, reboot without disks and update firmware, power down, put the disks back in, turn the SAN on again..
I will re-read the documentation many more times again.
Are the 2050 and 2052 controllers the same??
Or a different part number for a 2052 controller??
Controllers are expen$ive!!
