Changing a PowerFlex 753

Hello Friends

I need to change a discontinued PowerFlex 753-NET-E for a newer 753.

The PLC is a CompactLogix 1768-L45 with RSLogix5000 v20.

The old VFD has revision 9 and in the software the higher revision is 13. The new drive is revision 14.

How difficult is to change the drive?

Should I update the revision in RSLogix?

Any ideas would be appreciated.

Thanks in advance.
