Replacing doser 2 with 2.1 slave with p4

This is the method I plan on using

1 back up all settings to file
2 update the WiFi module on p4
3 update p4 operating system to latest firmware
4 restore settings and reboot system
5 empty KHD completely
6 enter connected devices and disable KHD
7 remove devices from pab system
8 switch power off at power bar for KHD
9 physically change the devices and reconnect
10 reassign pumps and calibrate
11 flush and take measurements.

If I’ve somehow missed a step please inform me.

Many thanks
Jason
