We’d like to migrate from ATA to ATP. We did the sizing exercise using the tool when we first installed ATA. Could we just replace the ATA gateway with the ATP sensor and be good, or do we need to redo the size calculations?
@AndrePKI Redo. The sensor works based on different sizing.
For low traffic scenario you might need to boost the machines, for high traffic you will probably have "left overs" as the sensors are optimized for high traffic.
If you ran the sizing tool once and the network did not change much, you can check if the excel output has a tab for AATP in addition to ATA, if it does, you can get insights from it, but if a long time has passed, it's best to re run the tool.
