Is there a Schneider Electric document detailing the process in upgrading a G3 ENC-410 or ENC-520? There is no such document in the G3 installation zip file.
Product Marketing did not generate an upgrade document as was done with Niagara R2.
Use Tridium's 'startup' guide for the ENC. It is not an 'upgrade' guide but the steps are similar.
