F.A.Q
How to filter files when migrating Linux?
Before executing go2ucloud.sh, add a line excludeRulesFile=“/root/myRules.txt” in agent_config.conf.
The myRules.txt file contains filter rules, as follows:
| Rule | Description |
|---|---|
| *.o | Exclude all files ending with .o |
| /data/*/test | Exclude test file or folder that is one level down /data directory |
| /foo | Exclude file or folder named foo under root directory |
| /foo/**/bar | Exclude bar file or folder under /foo directory and all subdirectories |
| foo/ | Exclude all folders named foo |
| test.txt | Exclude all files named test.txt |
| testdd | Exclude all files or folders named testdd |
How to exclude disk symbols such as D and F when migrating Windows?
Before executing go2ucloud.bat, add a line winExclude=“D,F” in agent_config.conf.
Note: Scenarios with multiple disk symbols for a single device are not supported.
Can USMC migrate GPU machines?
Yes, but it is not open on console. Users can refer to API to create migration task by themselves.
Note: UCloud Global has proportional requirements for CPU/Memory, GPU, if you are unfamiliar with them, you can apply for technical support.
What factors affect the speed of USMC migration?
The main factor is the actual transmission speed depends on the minimum value of the outgoing bandwidth of the source (your own host), the incoming bandwidth of the destination (step3-host configuration), and the bandwidth limit (step3-migration configuration).
Secondly,
Linux migration is based on file transfer, mainly affected by the actual occupied space of the internal files of the system, in addition, a large number of small files also will slow down the migration.
Windows migration is based on block transfer, mainly affected by valid clusters, if there is no disk fragmentation in the system, the migration speed is roughly proportional to the actual disk usage.
If it is cross-region migration, such as Alibaba Cloud Hangzhou migrating to UCloud Global Hong Kong, due to network latency/fluctuation, the migration process may be very long, please be patient, or try to improve network quality.
Can USMC keep MAC address unchanged?
Yes, but this feature is not enabled on the frontend. If necessary, you can call the api or apply for technical support.
On the support scenario page, I found that Ubuntu22 is supported, but there is no mention of Alibaba Cloud adaptation, can it be migrated?
Yes, you can select IDC when creating a migration plan.
For some cloud manufacturers with many users, USMC will do further adaptation, such as uninstalling Alibaba Cloud’s monitoring agent, etc., to give users a better migration experience.
If your cloud provider is not marked for a certain system, you can try to create a migration task with IDC as the source. If you have any questions, you can contact technical support.
When migrating the Windows system, you can select any source.
On the support scenario page, I found that there is no support for Debian12 and other systems, can it be migrated?
No, you can seek technical support feedback, USMC will contact you immediately after support.
On the support scenario page, I found only Server class of Windows, I have a home machine with Win7/8/10, can it be migrated?
No official support for now, you can seek technical support.
After launching the script, I can’t see the agent going online on the console?
First try to refresh the webpage, if it still doesn’t work, please refer to the network requirements in Migration Note for testing.
After migration, I cannot use the password set in the step of creating the task to login?
Generally, it is because some kind of security policy is set within the OS of the source machine, such as Windows disabling the execution of bat/ps1 scripts.
You can first try to login with the password of the source machine, or seek technical support.
