#1091 Add note about `uponReceiving` being unique to the migration notes + docs Issue created by TimothyJones Since changing to the rust core, it is important that the value of

uponReceiving

is unique. This is because (I believe) it uses that field to determine if the interaction should be updated or added to the pact file. I think the ruby core didn't do this (or used some other method to determine whether two interactions were the same). This information should be: 1. In the migration guide 2. Called out in big letters in the documentation pact-foundation/pact-js
