This document describes how to change the instance network type and modify the instance access address.
Note:Modifying the network configurations of an instance is highly risky. Do so only during off-peak hours. After modification, unless the original IP is assigned to another service or a custom IP repossession time is set, the original IP will remain valid for another 24 hours by default. We recommend you modify your business configuration accordingly as soon as possible.
You can modify the private network address of a TencentDB instance in VPC.
You can switch a TDSQL for MySQL instance's network between VPC subnets.
Note:
- The original IP address remains valid for another 24 hours by default after the network is changed. Change your business IP address accordingly within 24 hours.
- You can also set Valid Hours of Old IP to 0–168 hours. If it is set to 0 hours, the IP is released immediately after the network is changed. This may affect your business.
- As the product supports an intra-region active-active architecture, we recommend you choose a VPC subnet in the same region as your business server or the source node.
Note:
- The original VIP address remains valid for another 24 hours by default after the network is changed. Change your business IP address accordingly within 24 hours.
- You can also set Valid Hours of Old IP to 0–168 hours. If it is set to 0 hours, the IP is released immediately after the network is changed. This may affect your business.
- As the product supports an intra-region active-active architecture, we recommend you choose a VPC subnet in the same region as your business server or the source node.
Note:
- The switch from classic network to VPC is irreversible.
- After the switch, VPC access will take effect immediately. The original classic network access will be retained for 24 hours; therefore, other instances associated to the instance should be migrated to VPC within 24 hours so as to guarantee uninterrupted access.
- As the product supports an intra-region active-active architecture, we recommend you choose a VPC subnet in the same region as your business server or the source node.
