I would migrate, rather than translate.

Depending on the Cisco 7000 HSSI and/or AIP microcode, an ATM NAP could
migrate a PVC at a time or the whole NAP at once.

I assume that this migration will occur before NAPs become very large.

[By the way, translation between RFC 1490 (NLPID) and RFC 1577 (LLN/SNAP)
is still an issue for frame relay interworking units, even if it isn't
required for 1490-1577 migration in an ATM-only NAP.]
