Upgrade with existing campaign projects or requests

If you upgrade Marketing Operations system that is integrated with Campaign and you have existing campaign projects without corresponding linked campaigns, create the linked campaigns before you upgrade to Marketing Operations. Likewise, if you have existing project requests for campaign projects, accept or reject the requests before you upgrade to Marketing Operations.

If you do not link them before you upgrade, then when you attempt to create the campaigns for these projects or accept the requests after the system is upgraded, the campaigns are not linked properly to the Marketing Operations projects.
