Can I move an existing Azure subscription into a CSP Azure Plan?

Yes, this is a common migration path. Microsoft supports transitioning an existing Azure subscription (including older CSP subscription types) into an Azure Plan under a CSP partner.

What to expect

• Your resources, resource groups, and configurations are preserved through the transition.
• There may be a short administrative process to complete the transfer, best handled with your partner's help to avoid any billing gaps.
• It's worth confirming in advance whether any resource-specific settings (like reservations) need special handling during the move.

This is generally a low-risk, well-supported migration path rather than a rebuild.
