I have a project coming up that was programmed in Step7 5.6, WinCC 2008 Flexible, and Scout 5.2. I currently have licenses for Step7 Pro and WinCC Professional (TIA portal). Do i need to also purchase a WinCC Flexible 2008 license or should i migrate the HMIs to portal in the the event i need to edit or replace an HMI? Should i get the standalone version of Scout or the TIA version? Can both the TIA and Standalone be installed at the same time?
