I believe you are referring to the Standard User License and Power User License that existed pre-7.x versions. So there were two licenses before 7.x version and not in 7.x version. These licenses were as below,
1. Standard License (the one you referred as Casual) was for the browser/HTML interface and the Power License was to access the Workbench interface. This was until 6.0 version.
2. From 7.0 versions (and actually some part of it was modified in 6.0 version as well) - The Power Licenses are totally removed, since most of the end user application features are transferred to the browser interface from the Workbench interface.
3. Previously, there were three Power Licenses, for, - Demand Management Standard and Power separte licenses - Deployment Management Standard and Power licenses - Project Management Standard and Power licenses
4. Now, the licensing model is changed to as below,
. Application licenses (DM, PM, PFM, TM, etc.) . User Administration license and . Configuration license
So the conversion of licenses from 6.0 to 7.x will work like this,
- For each Demand Management Standard License and Power License (so two license for one user) will be converted into a single Demand Management license (so only one license for each user). This will reduce the overhead of license maintenance and extra cost of purchasing the power licenses.
- Similarly, for Project Management and Deployment Management also same thing will happen.
When you request HP for the new license key for the 7.x, HP will automatically convert all these licenses or you can also request HP separately to give you the break-up of your new licenses based on your earlier licenses of 6.0. HP does not charge for the license conversion and license upgrade (to say) for 7.x. That was my understanding when upgrade earlier from 6.0 to 7.x versions, HP will be able to confirm you the exact details based on your licenses.
