Decision record · “Re: Re: Piraeus cutover — schedule”
The cutover moves to 15 October
What was agreed, who agreed to it, and the two questions the thread never answered.
The Piraeus cutover moves from 28 September to 15 October. The Limassol site stays on the original date. Customs documentation runs in parallel on both systems for the first two weeks.

How the thread got there
-
11 August · Elena opens the thread
Flags that the customs module will not be tested before 28 September. Proposes nothing yet.
-
13 August · Andreas
Argues for holding the date and cutting the scope instead. Three people agree in the next four messages.
-
16 August · Elena, with the vendor's reply attached
The vendor confirms their change freeze runs from 25 September to 9 October. Holding the date would mean cutting over with no vendor support. This is the message the decision turns on.
-
18 August · Marios
Objects on cost: two extra weeks of parallel running was never budgeted.
-
19 August · Andreas changes position
Withdraws the hold-the-date argument and proposes 15 October, keeping Limassol on 28 September. Elena agrees the same afternoon. Nobody contests it after this point.
-
21 August · Marios
Withdraws the cost objection once the parallel run is capped at two weeks, and takes the budget action himself.
-
