Re: how to open customize an existing projects site template in project server 2019 ?

Hi Basim2245 ,

I've not specifically looked at Project Server 2019 as I've only used Project Online for the last 6 to 7 years but as far as I know, there is no difference in terms of Project Sites between PS 2016 and PS 2019. Ever since Project Sites were introduced back in Project Server 2007, or even Project Server 2003, the existing sites linked to Projects would not get updated with a new template. It would only be new project sites created after the new template was set on the EPT. This is true for Project Online also.

To update existing Project Sites, you either do it manually or write a custom app / code to roll out the changes to the existing Project Sites.
