Most of our SSIS packages written in BIDS for SQL 2008 use Package Configuration where the values are pulled from either a configuration table, XML, or an Environmental Variable on the OS, but when these are converted to SQL 2012 and converted to Project Deployment Model the variables in Package Configuration are just converted to Parameters and the process that updates these values from the external source is lost.
So is Package Configuration deprecated? I understand the new model in SSISDB with Environments and so forth, but given our original standard was that all SSIS packages pulled from a central configuration table this seems to be impossible to do with Project Deployment in SSIS on SQL 2012. Also I've tested deploying the Packages to SQL outside of SSISDB which does maintain the Package Configuration options, but then we loose the benefits that come with SSISDB in SQL 2012.
Probably just have to weight the benefits of each, but I'm just curious if there's been any talk at MS about Package Configuration being deprecated where eventually Project Deployment will be the only option.
