I think that's a common strategy. When Nationwide recently changed their logo they sent everyone an email and explained they were working through changing signs at individual branches.

However, they said if people were due a new card soon it may have the old logo, as they would use existing stocks first.

Same with coins, notes, stamps etc. with a change of monarch.

I think the Queen died around a year after the new logo was formally introduced, but think it will be a tight (and very long and slow) race to see which update is completed first.
