Hi, We are developing a custom heat resource plug-in and wondering about how to handle plug-in upgrades. As our product's object model changes with new releases, we will need to release updated resource plug-in code too. However, the "properties" stored in the heat DB for the existing resources, whose definitions have been upgraded, need to be updated too. Was there any discussion on this? Thanks, Praveen Yalagandula Avi Networks -------------- next part -------------- An HTML attachment was scrubbed...
