My First Days CAF GP process

Hi Experts,

We are using the My First Days CAF Process in Employee Self Service. It is working good in production system. We have to make a change to one HTML page using by the process. I made the change and activated HTML content page and the total process.

Here is a question,

Users already started the GP process and completed certain activities. because of the new version of the process, they have to start the process all over again. Is there any setting on the process to make this not happen.

Thanks!
