    What risks do I face if I don't upgrade?

    The cross-region peering connection will be discontinued on October 31, 2022, and will not be maintained later. If you continue to use it, you will face operational risks. In extreme scenarios, it may cause business failures and cannot be quickly recovered.

    What exactly does a cross-region peering connection refer to?

    The peering connections connect two VPCs through the private network and are divided into intra-region and cross-region connections based on the VPC regions. Tencent Cloud is going to discontinue the cross-region peering connection.

    Will the intra-region peering connection be discontinued?

    No. Only the cross-region peering connection will be discontinued this time.

    Can all plans support smooth migration?

    Yes. The migration plans in Migrating the Cross-Region Interconnection Service to CCN all support smooth migration. The migration may be jittery, but will not cause service suspension.

    • VPCs are interconnected when the two-way routes between VPCs are directed to the peering connection and CCN instances separately.
    • One or two packets may be lost when routing is enabled.

    Will the cost increase if I change a cross-region tunnel to the cross-region CCN connection?

    No. Under the same service availability (99.95%), the price of CCN is lower than that of Peering Connection. CCN provides three service levels for your choices based on the business availability. For CCN billing details, see Pricing.
