could you please keep older NG-Versions in the Azure Cloud available for installation, like other vendors also do for their installation images? Currently older versions (e.g. 6.0) is no longer available since the release of 6.1.
I understand, that 6.1 integrates better in the the Azure Cloud that 6.0 does, but as there are limitations when integrating newer Firmware releases (6.1) into older customer management clusters (e.g. 5.4), being forced to use the newest Firmware release does cause additional installation and managment overhead.
