If you experience any issues at this stage, you must contact the IT support consultant assigned to your integration so they can resolve it.
Because of the nature of integration, DotActiv allows for a little bit of leeway up until official sign-off. Even after sign-off, there is leeway for the first six months. However, it is within reason.
After that, since you are full-fledged production environment, DotActiv is stricter.
