Can Cirrus Migrate Cloud migrate containers? Cirrus Migrate Cloud (CMC)'s block-level storage migration can migrate any block devices on the server, including the boot volume. Therefore, while it does not migrate on a per-container basis, any containers and container volumes within the selected migration volumes will be migrated.Few readersMy migration session's status is "IN ERROR". What does that mean?
This article describes the common causes of migration errors and appropriate actions to be taken to resolve them. Migration Status "IN ERROR" When one or more volumes within a migration session encounter migration error, the migration session will become in error. Once a migration volume is in error, synchronization will be suspended after appropriate retry attempts. However, unlike a "migration failed" status, synchronization progress is preserved when a session is in error. OFew readers

Migrating Boot Volumes
This article describes the details and best practices on migrating boot volumes (OS Volumes) with Cirrus Migrate CloudPopularHow to establish host-to-host (H2H) network connections for remote migration?
How to establish host-to-host (H2H) network connections for remote migration? What is H2H Connection Host-to-Host (H2H) connections are optimized one-way TCP-based network connections that cirrus-migrate-cloud uses to facilitate remote-migration, which features always-on compression and encryption. By design, NO PRODUCTION DATA / I/O leaves the production network during the entire migration phase. As a result, direct connectivity between the source and destination host is requPopularHow to open up TCP ports in Linux/Windows OS-level Firewall?
if this host is designated as a receiver for establishing an H2H connection, the following system commands can be used to open up port 4996 for Inbound connection. RHEL-based Linux 7+ (Redhat, CentOS, Amazon Linux, Rocky Linux, Fedora)Some readersHow to take an X-Ray for Cirrus Support?
When a support ticket is opened with Cirrus Data Cloud Support Team, an X-Ray is often requested. An X-Ray is a support package that consists of detailed application logs and runtime data such as migration session status. Taking X-Ray from Cirrus Data Cloud X-Ray can be taken via Cirrus Data Cloud UI. To take an X-Ray, go to your host's details page, click on the vertical 3-dot icon ⋮ on the top right corner, and select DowFew readersHow to Unmask a Disk that is Masked by CMC Migration
During the various phases of a CMC migration process, the source and/or destination disk is masked to prevent accidental usage by the user. Further, any snapshot taken by the destination storage (when a CMC Integration is invoked) is also masked unless there is an additional Action defined to unmake the destination prior to calling the snapshot (and in that case, yet another Action should be defined following the Snapshot action to mask the destination again). All these necessitates the availaFew readersHow Do I Get A License for Cirrus Migrate Cloud?

When creating a migration session, a migration schedule can optionally be set up to: Only start migration after a specific absolute time Use different iQoS Impact Level at different time of the week. Suspend migration activities at different time of the week. If migration schedule is NOT enabled for a migration session, the session will be migrating 24/7 at the selected iQoS Level.Few readersHow to Generate Migration Reports?
Migration Reports are print-able and self-contained reports that can be generated from Cirrus Data Cloud for your migration session. A migration report will include detailed information on a particular migration session, including its configuration, current status/statistics and historic events. This feature is only available for CMC version 5.1.0 and above Who Can View/Generate Migration Reports All members of a project can view all previously generated Migration Reports.

During remote migration (including compute migration), operating systems are often migrated to different hosts, environments and/or architectures and therefore require configuration changes post-migration. These changes may include driver installations, network configuration changes, clock changes, authentication configuration changes, etc. Cirrus Migrate Cloud (5.1.0+) provides a convenient mechanism for you to automate these configuration changes.
