I'm tiptoeing through my upgrade to 2017.
Presently, we have a PDM Standard 2016 vault and three seats in use. I've upgraded the License server to 2017 without issues. The next step would seem to be upgrading the DB and Archive servers. I'm concerned that if I do this, my users won't be able to get into the vault until they upgrade their PDM clients to 2017.
Is that the case?
All servers and clients must be on the same version and service pack for PDM 2016 and earlier. PDM 2017 allows you to mix service packs but still requires the same version. Therefore, you will have to upgrade everything from 2016 to 2017.
