The school district I work for has decided to move to GMail away from GroupWise. The decision was made by a few members of a committee and is in the final stages of migration. Now that the move is going forward a large number of my user base is upset with the move. The minority wish to move to GMail a larger group wants Exchange/Outlook and my older user base don't want any changes due to having to start over with their accounts. We don't have any plans to Migrate the data over due to Cost.
I am wondering if there is a way to do a split delivery via rules or if the complexity and issue involved is just not worth the trouble. I have a large user base that is using Office 365 services and are not planning on Google Services at all. I don't want to cut off my Google user base but also don't want to cause problems with the delivery. The Supt. made the decision to move to GMail and we have provided both Office365 and Google Suite accounts for several years but haven't move e-mail for a number of reasons.
I am a major user of GroupWise and have been for a number of years going back to 6.0 days or even before. I also don't want to go against what the Supt. and district wants. With that said I was hoping to find more information from those that have had to face this delima to see how they handled it. I have explored creating a GroupWise system for my personal use at home and may still do so since I like how my work flow currently works. But this wouldn't have any effect on this districts change nor those end users that are wanting to move to Office 365 and Exchange.
Any insight would be helpful.
