from gnuPG 1.47 to gnuPG 2.2.14

[currently using:]

openGPG: v1.4.7
winPT: v1.20

[updating to:]

gnuPG: v2.2.14

Q1. will there be any compatibility issues with my keys generated with v1.4.7 when i begin to use gnuPG 2.2.14 ?

Q2. i was using WinPT. will Kleopatra and/or GPA be able to import those keys that WinPT made use of?
