Kurt is planning to upgrade his Security Management Server to R81.

 The lowest supported version of the Security Management that can be upgraded to R81.X is R75 Gaia. This means that the Security Management Server must be running on the Gaia Operating System and have a version of R75 or higher. R76 Splat, R77.X Gaia, and R75 Splat are not supported for upgrading to R81.X1.
