as above. The servlet would be of class org.apache.sling.api.servlets.SlingSafeMethodsServlet.The OSGI component would be of org.osgi.service.component.annotations.Component.Thank you. 

is there something similar for on-prem upgrades (example: 6.3/6.4 to 6.5)? Thanks

But is code rebasing part of the migration process? I checked the info from adobe.com but it's not so clear. Thank you. (I did a migration from 6.2 to 6.4 long ago but I cannot remember if the code was rebased)

I got confused what Adobe meant by "touch". In linux, touch normally means the timestamp of the file changes. Thank you for the comprehensive reply.

Do I need to rebase my code to the latest maven project archetype or the BPA/pattern detector will do it for me via the recommendations/findings?  Thanks

Thanks for the extensive reponse. Just a clarification if you don't mind. When you said "Edge Delivery", do you mean the new/newish "Edge Delivery Service" (EDS) from Adobe. Or do you mean the "edge delivery" that's normally associated with CDNs? If it's EDS from Adobe, I had a look at it last year ...

But what about other settings that can be set in both locations? settings like headers and etc

I'm just trying to understand .stat files (specifically /statfileslevel) and I don't understand this example provided by Adobe. screenshot is from => https://experienceleague.adobe.com/en/docs/experience-manager-dispatcher/using/configuring/dispatcher-configuration#invalidating-files-by-folder-level...

I've seen the best practices mentioned by Adobe. BUT are there other performance checks/enhancements I can make on my frontend/backend code? The ones that I can think of are:checking the logs/monitoring tools available in the instancelighthouse metricsAnything else? Thanks!

if allow.empty is enabled BUT I have entries in allow.hosts.regexp, is my instance still limited to the hosts lin the allow.hosts.regexp list or will the instance accept any request coming from anywhere? Thanks!
