Successor model: the destination, named or not
A successor is the model a retirement notice names as the destination. One dated row in this register carries one, and it is a later version of the same model. Everywhere else the ending arrives without a destination and the customer chooses, which is the expensive half of a migration. As of 2026-09-22.
| Settled by naming one | Still open |
|---|---|
| Where to start testing | Whether prompts carry over |
| Which version the vendor expects you to use | Whether pricing is comparable |
| That somebody thought about continuity | Whether the move is performed for you |
| A candidate, before the runway is spent | Whether the successor has its own date |
Inclusion rule. Filled only where the notice that announced an ending also names what follows it. A newer version existing is not a published statement. Order. What naming one settles first, then what it leaves open.
1A runway cannot be spent without a candidate
The work a notice period is for is testing whatever comes next, and that cannot start until somebody decides what next is. So a date without a destination hands a reader the easier half of the problem.
Five months of warning is worth much less when the target is unstated, because choosing wrong spends the runway twice.
2The obvious guess is still a guess
Most readers will assume the maker's newer model is the route, and most will be right. Writing that into a register would make every such cell unverifiable, which is the trade refused in every column here.
The cost of guessing is not abstract. A team that migrated to an assumed successor and found the pricing or region coverage different has spent its runway on the wrong test.
3Naming is not moving
Even where a successor is named, nothing says the platform performs the change. One entry states outright that migration will not happen automatically, which is more useful than leaving it implied.
So a complete disclosure has three parts: a date, a destination, and who does the work. No entry in this register publishes all three.
A definition rather than a dated entry: no line above is a vendor statement. Where this word turns up in a real notice, the wording and the date are on the named replacement column. Nearby terms: Silent update, Endpoint, Published weights.
