56. How do the notice period and the transition period relate to one another?

Article 25 of the Data Act provides that the notice period begins once the customer notifies the provider of data processing services of their desire to switch to another provider or to an on-premises ICT infrastructure. Switching should be completed by the end of the transition period, which starts after the end of the notice period (maximum 2 months). During the transition period (maximum 30 calendar days), the provider must carry out the actions needed to enable the customer’s switching – in close cooperation with the customer themselves and, where applicable, with the customer’s new provider. The customer has the right to replace the 30-day transition period with a longer period. The provider can only extend the transition period if the provider can, within 14 days during the notice period, prove that a transition period of maximum 30 days would be technically unfeasible. In this case, the transition period can last a maximum of 7 months.
