Hi,

We are in the middle of testing the migration of our Exchange 2010 environment to Exchange 2016 using a lab copy of the live environment.

We have integrated the Exchange 2016 servers and migrated the public folders. We can create new oganizations and mailboxes for them which appear on the new servers.

However we receive an error when trying to create a new mailbox for customers who were created on the old Exchange 2010 servers:

Server was unable to process request. ---> Can not create 'Hosted Microsoft Exchange Server 2016' provider instance with 'SolidCP.Providers.HostedSolution.Exchange2016, SolidCP.Providers.HostedSolution.Exchange2016' type ---> Exception has been thrown by the target of an invocation. ---> The type initializer for 'SolidCP.Providers.HostedSolution.Exchange2016' threw an exception. ---> Could not load file or assembly 'System.Management.Automation, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies.

I'm guessing that this is to do with us not updating the SQL database correctly. We have changed ServerID in Packages and HostingPlans to be the new EX2016 Virtual server and ProviderID in Services to be 92 (Exchange 2016). I found a page which mentions the ServiceItems table but couldn't really see what was needed to be changed.

Have we missed something or changed something we shouldn't have? I could really do with a definitive list of which SQL tables and columns need to be updated.

Thanks,

Mark
