Hi Ted,
No problem, just follow RFC 7084.
Old GUA prefix could be used up to the point that WAN link would be reconnected and GUA would be changed with 37% probability.

From standard point of view
local traffic should not stop after CPE would lose uplink,
Because internal CPE switch should still switch traffic
After internal CPE router would stop promoting itself a router for this link

That’s at layer 2. At layer 3, we need a stable prefix so that the traffic continues to flow during the external renumbering event without breaking internal traffic.
