This procedure upgrades a point-to-point configuration (two nodes) or a
linear ADM configuration (three or more nodes) to a two-fiber
MS-SPRing manually, that is, without using the in-service topology
upgrade wizard. Use this procedure if the wizard is unavailable or you
need to back out of the wizard.

If the span is an STM-16, no more than 8 VC4s can be provisioned on the span. If the span is an
STM-64, no more than 32 VC4s can be provisioned on the span. If the span is an STM-4, no
more than 2 VC4s can be provisioned on the span.
