Vertaling van "devait durer environ " (Frans → Engels) :

Le plan initial consistait à effectuer la migration de quinze États membres (le nombre d'États membres à cette époque) au cours d'un processus qui devait durer environ huit heures.
The initial plan was to have a migration of 15 Member States (the number at that time), during a process that should take around 8 hours.

Pour remettre les choses en contexte, le gouvernement nous a dit il y a environ trois ans que ce projet devait durer environ 18 mois.
I have to say that when we put this in context, it was something like three years ago that we were told by the government that this would be about an 18-month process.
