step0 Migration Notice

Pre-migration Notice

System

Use the appropriate method to back up data, such as VMware snapshots, Windows restore points, etc.
It is recommended to turn off antivirus software to avoid affecting the startup of the migration agent

Network

The source machine does not need to open any inbound ports, but it needs to be able to access the USMC management service address

The migration process agent will occupy some resources of the source machine, such as CPU/Memory/Disk IO/Bandwidth, please be aware
Any operations on the transfer machine usmc-stopover-do-not-delete are prohibited, such as shutdown/reinstallation/change password/unbind EIP, etc.
During Windows system migration, please do not close the cmd window that appears after launching go2ucloud.bat, keep it open until the migration is completed
USMC migration supports breakpoint resume, but there is no need, do not restart the agent on Linux or Windows end to prevent accidents
When an error occurs during migration, enter the usmc-xxx directory in Linux, or directly in the opened cmd window in Windows, cat usmc_agent_log.txt and provide it to the technical support

Linux migration is based on file synchronization, Windows migration is based on block synchronization, users are responsible for verifying data consistency
USMC is only responsible for pulling up the system/network on the destination side, the impact on users’ own business is hard to estimate, please fully test before putting it into a production environment.
