Upgrade from 5.6.1 on a standalone separate 6.2 instance
We have many sites running on 5.6.1 and we successfully did the in-place upgrade. As each site takes time to test, we would like to deploy it site by site on production by switching DNS to point to the new 6.2 site once thoroughly tested.
Can we create packages from 5.6.1 and deploy it in the new instance. If we are not bothered about versions and audit, is it fine to deploy the code and content packages (including DAM) to the fresh instance. Could someone please confirm if there will be any impact following this approach as the underlying architecture is different(CRX2, CRX3).
Also for Delta content from 5.6.1 production, we are thinking of using the ACS tool - http://adobe-consulting-services.github.io/acs-aem-commons/features/query-packager.html
