Due to company reasons, we want to migrate the self-built TIDB cluster from Alibaba Cloud to Tencent Cloud.
Dear experts, do you have any good solutions? Has anyone done cross-cloud migration before?
Requirement: uninterrupted business
For example, similar to creating a new cluster in another data center (Tencent Cloud), after setting up the cluster, perform a full backup and restore using BR.
Refer to this, cross-cloud migration and cross-data center migration should be similar, mainly limited by the network
Call Tencent Cloud customer service, and the representative will send various quotations. You can purchase traffic packages annually or pay as you go. Whether you write code or not, they offer partially self-managed servers and fully managed services, with options for full or partial manual service management.
I remember when Oracle used to do remote disaster recovery, they would copy the data to multiple hard drives, take a bunch of hard drives on a plane to the remote data center, and then restore Oracle there. The logs ran for a day, and then they caught up with the primary database.
If the data volume is very large, data synchronization may take many days.
The fastest solution for data migration currently is physical transportation. 
Nowadays, everything is on the cloud. Using DTS, the speed is acceptable. Cross-account transfer is much faster than by plane.
Yes, for example, the data from a hard drive can be transferred directly using DTS, and then you can take a flight with a large package of hard drives.
