We are a surveying and mapping company and have been using UAVs P3P and P4P with DroneDeploy, Pix4Dmapper, map pilot etc. as manufacturing of p4p has been stopped, we are planning to buy p4p v2. Hence I'll be very happy to get feedback as well as names of flight planning software for the P4P V2.0. Thanks  

Hi. Thank you for reaching out to DJI Forum. With regard to using a third party mapping application. I hope that our valued DJI co pilots can provide you the best recommendation for this inquiry. Just a friendly reminder to please fly with caution, when using a third party application. They may work but we cannot guarantee the stability and comparability during flight. Thank you and safe flying.

The v2 P4 pro is only trivially different from the original version.
You can use exactly the same software for the V2.0.
You wan't have to change anything

Keep doing what you are doing. It’s essentially the same machine.

As stated,  the V2 is operationally the same as the V1.   I now keep the V1 as a backup unit to the V2.

You are good!
