I am attempting to migrate an on-prem Dynamics CRM to the cloud version using Integration Services. Most of the entities have been straightforward – I create a copy of the table, update any fields that need updating (for example, update the OwnerID field to match the cloud guid for that user, etc). Then, using Kingswaysoft in Visual Studio, I push the staging table up to the cloud CRM. However, now we are trying to migrate attachments and emails and keep running into issues. Note – I am a SQL developer not a CRM admin, so I don’t have a great grasp of where this information is stored (Emailbase, ActivityMimeAttachment, Attachment, FileAttachmentBase, ActivityPartyBase). I suspect the order of migration is probably key to this process, but have been unsuccessful in finding a guide that explains this.
