Upgrade to AEM 6.3 Tips
While upgrading from older version to AEM 6.3 you can use following process as described by Adobe.
However, there are few things very minor but tricky, you'll not find there.
1. AEM 6.3 is stricter. If you miss to close a single tag on you sightly template, your whole page/functionality will break. So always scan your HTML before panicking.
2. I would want to believe that if you're on AEM 6.1 you've been extensively using showhide dropdown. Here, in the tabs those are part of this functionality has to have class , hide and not hidden.
3. In earlier versions, when there was null resource, there wasn't any exception thrown in the Use class, but now, there will be. So always provide null pointer check before starting to use the resource.
4. Set value of deleteHint=false if you can't see values of dropdown in multifield are not getting saved.
5. granite/ui/components/foundation/form/dropdown should be replaced with granite/ui/components/foundation/form/select
