We are planning to run a technical as-is upgrade of our website from CQ 5.2 to 5.6 without changing functionality. From a planning perspective:
1. What are the considerations we need to address to understand the required effort and time required for the upgrdade?
2. Dow we need to run any migration of the content? how long does it take for a medium complex environment, say for a single system environment (DEV or Prod)
3. What are the risks, if the content is considered highly bespoke?
thanks
