The scenario of migrating calendars from Project Online to the Dataverse environment in template format
The Calendars Synchronization feature as part of the Project Sync add-ins allows you to transfer working calendars of Projects and Resources between Project Desktop files and calendars of projects and resources published in the Project for the Web Power Platform environment
A separate scenario also supports the migration of corporate and resource calendars from the Project Online tenant to the Dataverse environment in calendar template format.
To perform this scenario, you must perform the following steps:
1. Connect to an available Project Online tenant using the Project Professional application.
2. If you need to migrate enterprise corporate calendars, open any project that will provide access to them through the Corporate Global Template for Project Professional. To copy customized resource calendars, open a project that contains the necessary enterprise resources from the Project Online Resource Center.
3. On the Project Sync toolbar, click the Calendars Synchronization button to open the settings window.
4. In the configuration window, choose the third option of synchronization scenario - Upload as Dataverse Calendar Templates
5. In the Dataverse column for any calendar displayed in the Desktop column, select Create New Template
6. Start exporting the selected calendars' settings with the button Upload Calendar Templates.
7. Check the creation of new calendar templates in the general settings of Project for the Web on the Calendar Templates page. New calendar templates will be created in Dataverse with valid Project Online calendar names.
