After a few weeks of experience supporting the Resource Management features of Project Online I decided to post a blog covering some details behind the resource plan migration that happens after activation of the feature. Part 1 is over on the Project Support blog at http://blogs.technet.com/b/projectsupport/archive/2015/10/21/project-online-resource-plan-migration-expectations.aspx. Part 2 will come soon when I’ll cover a few things you can do with your migrated plans once they are resource engagements.
One thing I’ll pull out here is an OData Url that you can use to see just which of your current Resource Plans will get migrated
https://contoso.sharepoint.com/sites/pwa/_api/ProjectData/Projects?$select=ProjectName, ProjectResourcePlanWork, ProjectModifiedDate
Any where the ProjectResourcePlanWork is 0 will not come across – and also check the modified date to be sure you not only have published resource plans, but recently published resource plans.
I’ll also be touching on this topic at my session in the Virtual Project Conference – today, October 22nd at 4pm PST. Looks like the popularity (of the conference – not my session) has closed registration right now https://projectvirtualconference.com/register/ – but I understand all the sessions are recorded so you can watch later if you don't get to see it live.
