We are planning to move to a different roaming platform, should we inform DCS?

Yes. When you migrate between two roaming platforms, the commercial offboarding from the old platform and onboarding to the new one need to be handled in coordination with DCS. The good news is that for platform-to-platform migrations, a separate technical onboarding and offboarding is generally not required - the commercial process with offer cancellation and acceptance covers it. But we still need to be aligned, so please notify us in writing as soon as you know.
