The updated DMS service in EU-DE & EU-NL will generate new T-Systems SSL certificates after 07/19/2024.
For new instances after 07/19/2024:
The new certificates will be automatically generated after this date and can be used on the client side.
Combining existing & new instances:
Both SSL certificates can be used in parallel by implementing a switch on the client side. Alternatively, can the SSL certificate for older instances be updated by raising a Service-Desk ticket. This procedure will require a DMS instance restart and will cause a minimal down-time.
