I don´t really think that your Universal 2.12 will work (as expected) with Satellite 10.2
Releases have 3 years of difference at least.
2.12 enviroments are NOT supported anymore. Still, you should try this.Maybe you are lucky and it works. Since Satellite just encrypts emais, your data will not be at risk.
