Hi Wes,

Seems to me that this could be heavily informed by historical data from
this earlier renumbering.

Do you have query rates over time for the old and new addresses since this
change in 2017?

Even if you end up with the same answer of 12mo, data supporting it may
give comfort to the community.

Maybe you make a call that once it’s at say 1% or 0.1% or something like
that, then it’s OK to turn off - and make a prediction for when that might
be based on the historical data.
