For projects imported from P6, all milestones besides the first start milestone and last finish milestone will be converted to Interim Milestones and have date mapping applied as follows:
- P6 Start Milestone without constraints β to IMS with Start of Next Day 
- P6 Finish Milestone without constraints β to IMS with End of Day 
- P6 Start Milestone with ALAP constraint β to IMS with Start of Next Day 
- P6 Finish Milestone with ALAP constraint β to IMS with End of Day 
Note: Learn more about the different types of milestones in Planera here
Change the Date Mapping of an IMS
- In the Canvas: right click on the IMS and choose "Date Mapping" from the context menu - If you are unsure of which date makes the most sense for your project, hover over the information icon for more information on your choices 
- In the Table: Use the constraint column to select either None-Next Day or None-End of day (EOD) for your IMS
