Upgrade Issue 7.3.1 to 8.6.2

We are upgrading pega 7.3.1 to pega 8.6.2 and we found a generic issue in most of the activities where allow invocation from browser is checked. After upgrade it is expecting to specify privilege for all those activities, is there any alternate fix for this to avoid updating manually for all the activities? Refer: Attachment

Another issue is @java is no more supported, similarly we need update all the activities manually.

What will happen if any of the OOTB rules falls under these fixes do we need to save them to our application rulesets and modify them?

@KiranKumarSangaraju Hi Kiran,

Can you please confirm if allow invocation from the browser is not checked before for that activity in 731?

Please follow the below link which explains a user must have a privilege if allow invocation is checked.

Thank you.

it was checked in 7.3.1 but in 8.6 it is asking for privileges. We will review all the activities through revalidate & save and fix them one by one.
