Q: Are windows and Linux platforms both block level migration? What about file level migration?

A: Both windows and Linux platforms are block level migration, and file level migration is not supported at present.

Q: System applications are block level, is file migration relatively simple?

A: Block level migration includes system and file migration. File migration is not currently supported.

Q: Is breakpoint resume a multi part upload?

A: The data is migrated in blocks and the progress status of migration is recorded. The upload migration resumes from the breakpoint of the last interrupt.

Q: What is the specific way to go back?

A: At any time point of migration, you can remigrate or migrate incremental data and perform data validation. The migration process does not affect or rewrite the source business system and operating system data at all.

Q: What is the difference between e Cloud server migration and Huawei SMT migration?

A: Server migration is a block level migration, which supports hot migration, incremental migration, verification, task evaluation management and other perfect migration functions. SMT Linux only has file level migration, windows only has block level migration, and does not support hot migration, incremental migration and other functions.

Q: Does migration need downtime?

A: No downtime is required during migration. At the end of migration, it is recommended to stop the business operation and then perform the end of migration operation; After the migration is completed, stop the source business machine and restart the target machine.

Q: How is the deployment of server migration different from that of normal migration?

A: The deployment of the source side and the server side is no different. The target side needs to use our preset image to create the target machine for migration

Q: What are the differences between different migration tools?

A: Select the corresponding image on the target cloud platform to create the target image or server image, and the relevant image path and version will be notified by email

Q: How to migrate Oracle RAC database cluster?

A: According to the whole machine backup, the database data can be recovered.

Q: How to migrate with Huawei, Alibaba, Tencent and other public clouds?

A: Build a good migration management platform, in Tianyi cloud, pull up the target virtual machine through the server migration target image, and directly migrate the source machine to the target virtual machine. Please refer to the installation and configuration manual and operation manual for details.

Q: Can only host and database be migrated?

A: The database data can be migrated according to the way of the whole machine.

Q: Can I migrate user disk?

A: Both system disk and data disk support migration as long as they are block devices. Support iSCSI / FC and LVM, dynamic disk, multipath disk and other disks.

Q: How to ensure the consistency of online migration data? Will windows have a large number of blue screens after migration

A: Online migration ensures data consistency through incremental data synchronization and unique snapshot consistency guarantee technology of e Cloud server migration. Both Linux system and windows system have gone through a lot of compatibility tests to ensure the success rate of migration. For special systems and unexpected configurations, most of them have corresponding processing methods. There will not be a large number of blue screens after windows migration.

Q: How long does it take to cut?

A: e Cloud server migration has an original migration evaluation technology, which can display the task time-consuming evaluation in real time for users to make decisions. The operation of business cutting corresponding to e Cloud server migration is "end". The user can evaluate whether the end operation is completed at a time acceptable to the user according to "how much time is needed to end at present" to decide whether to execute the cutting; If the time is too long, you can also perform "immediate incremental migration" to shorten the time required to end the operation to meet the user's expectations.

Q: How to migrate a device with a bare disk?

A: Tianyi server migration supports bare disk migration.

Q: How to migrate if restart is not allowed?

A: Linux does not need to restart; After windows has installed agent, it is recommended to restart and migrate again to use all migration functions of MoveSure. If you do not restart windows, incremental data migration will not be supported. In this case, you can choose to stop the business and make it no longer generate incremental business data before migrating, which will also complete the migration task.

Q: Need to manually create the same target operating system as the source?

A: No, you can directly start the virtual machine by using the target image published in the cloud market, or you can start the virtual machine by using the target ISO and image provided by e Cloud. No need to preinstall the system, no need to preconfigure the system and other complex operations.

Q: After migration, will the source host's license be migrated together?

A: Yes, but it may be necessary to resolve the change of authorization with the service provider. Migration is equivalent to changing the hardware environment of operating system and business system, which may lead to partial license invalidation.

Q: In the process of migration, the IP of each service is different, so the migration process is not a service IP, does it need to be reconfigured?

A: It is possible, if the service is bound to IP.

Q: Where is the server deployed?

A: On the cloud or other  IP systems with public network.
Q: 20 and 40g are migrated as 60g to the target side based on blocks. Is the remaining 20g formatted to the file system or not using the state to be formatted?

A: Unformatted

Q: If the source IP is statically allocated, will the IP be automatically acquired after migration?

A: It will still be static IP

Q: If you are using shared storage, is the migration process just a local disk?

A: e Cloud server migration supports the migration of block devices and volumes. Shared storage in the form of block devices can be migrated.

Q: Do you want to migrate with the operating system?

A: Yes, migrate the data on the disk along with the whole machine, including the operating system

Q: The old system doesn't support it. How to deal with the migration?

A: If it is an old system, it can be run in the cloud platform's supported OS list. Otherwise, it needs the cloud platform to add the OS to the support list

Q: How can we make sure that the customer's system of public cloud can be migrated to the platform of public cloud? Who will judge? How do users do self-service operation?

A: Public cloud vendors will provide a list of OS, and then we will enrich the display and description of migration services on the public cloud to make it easy to operate. For the OS that is not supported by some public cloud vendors, it is necessary to conduct technical research on the customer environment, and the cloud vendors carry out the secondary development and adaptation of the cloud platform. After the underlying support, it can be migrated.

Q: Can I join the migration of object storage?

A: Not supported currently.

Q: Can cluster database be migrated?

A: Yes, along with the whole machine.
