By all means, I didn’t mean to discourage you writing it for your own purposes, but I wouldn’t advise other sites to use it unless they’re familiar with the code and the data structure.
The bottom line is that the Reactions Plugin isn’t currently written in a way conducive to a stable migration that will work reliably across environments.
If anyone wishes to migrate from Retort to Reactions, Pavilion is handling these manually on a contract basis (email contact@pavilion.tech or PM me). If the Reactions Plugin is updated to allow for generalized migrations we’ll complete the migration work to make this freely available.
