We have an installation with Alfressco Community 5.2 that was done by our Systems team. We are thinking of purchasing the enterprise version, the ACS Starter plan. But we have some doubts: - It is compatible with having an Active/Passive environment - Will the migration process from ACommunity 5.2 to ACS starter 7 be painful? - Is the ACS starter installation on premise or does it have to be cloud? - Can my systems team continue to maintain the installation?
