Prioritizing migration of data associated with a stateful application based on data access patterns

A non-transitory machine readable medium storing instructions executable by a processing resource of a computer system, the non-transitory machine readable medium comprising instructions to:

• install an instance of the stateful application within the target virtualized environment;
• initialize a priority map for source data associated with the stateful application by establishing a priority for each chunk of a plurality of chunks of the source data by analyzing historical data access patterns associated with the source data;
• migrate the source data from a source data volume associated with the first computing environment to a target data volume associated with the target virtualized environment on a chunk-by-chunk basis by performing a background data migration process based on the priority map;
• facilitate usage of the stateful application concurrent with the background data migration process by abstracting a current location of a particular chunk of the plurality of chunks that is being operated upon by the stateful application including maintaining for each chunk of the plurality of chunks information regarding a migration status of the chunk;
• and
• periodically update the priority map based on observed data access patterns associated with the usage of the stateful application.

A system comprising:

• a processing resource;
• and
• a non-transitory computer-readable medium, coupled to the processing resource, having stored therein instructions that when executed by the processing resource cause the processing resource to:
• install an instance of the stateful application within the target virtualized environment;
• initialize a priority map for source data associated with the stateful application by establishing a priority for each chunk of a plurality of chunks of the source data by analyzing historical data access patterns associated with the source data;
• migrate the source data from a source data volume associated with the first computing environment to a target data volume associated with the target virtualized environment on a chunk-by-chunk basis by performing a background data migration process based on the priority map;
• facilitate usage of the stateful application concurrent with the background data migration process by abstracting a current location of a particular chunk of the plurality of chunks that is being operated upon by the stateful application including maintaining for each chunk of the plurality of chunks information regarding a migration status of the chunk;
• and
• periodically update the priority map based on observed data access patterns associated with the usage of the stateful application.
