Abstract

A migration plan is created that is based at least in part on an operator input. The resources of a destination file system are provisioned based on the migration plan. One or more processes to migrate the source file system for the provisioned resources of the destination file system are then configured based on the migration plan.

Claims (45)

1. A method comprising:

identifying a plurality of file system objects of a source file system for migration to a destination file system based upon a migration plan constructed for transforming one or more source file system objects from a source file context path and a source file type to a destination file context path and a destination file type as one or more migrated file system objects;

reformatting a logical structure of a source policy collection for the one or more source file system objects based upon the migration plan to create a destination policy collection for the one or more migrated file system objects for optimizing the destination file system, wherein the reformatting comprises:

de-duplicating policy entries within the source policy collection to create an equivalent set of policy statements for inclusion within the destination policy collection based on how an architecture of a destination filer hosting the destination file system applies policy entries to defined file system objects, wherein the de-duplicating groups multiple policy entries into a logically equivalent policy entry formatted according to a structure and syntax of how the destination file system applies the policy entries to defined file system objects; and

migrating, based upon the migration plan, the plurality of file system objects from the source file system to the destination file system as migrated file system objects which includes the one or more migrated file system objects.

2. The method of claim 1 , wherein the source file system has a different architecture than the destination file system.

3. The method of claim 1 , comprising:

migrating the plurality of file system objects over a plurality of sessions.

4. The method of claim 1 , comprising:

generating multiple sessions for migrating the plurality of file system objects.

5. The method of claim 1 , comprising:

migrating a first subset of file system objects, of the plurality of file system objects, corresponding to a first object container during a first session.

6. The method of claim 5 , comprising:

migrating a second subset of file system objects, of the plurality of file system objects, corresponding to a second object container during a second session.

7. The method of claim 1 , comprising:

migrating a first file system object from an object container on the source file system to a corresponding object container on the destination file system.

8. The method of claim 1 , comprising:

executing a walker to evaluate resources of a source filer hosting the source file system to identify the plurality of file system objects.

9. The method of claim 8 , wherein the walker executes an interface to access a log to identify the plurality of file system objects.

10. The method of claim 8 , wherein the walker executes a representational state transfer (REST) interface to access a health file to identify the plurality of file system objects.

11. The method of claim 8 , comprising:

executing the walker to identify structure information about the plurality of file system objects.

12. The method of claim 8 , comprising:

executing the walker to identify organization information about the plurality of file system objects.

13. The method of claim 8 , wherein the walker executes a Zephyr Application Program Interface (ZAPI) to identify export files associated with the source filer.

14. The method of claim 13 , comprising:

utilizing the export files to identify the source policy collection on the source filer for the one or more source file system objects.

15. A non-transitory computer-readable medium that stores instruction being executable by a processor of a computer system to cause the computer system to perform operations that comprise:

identifying a plurality of file system objects of a source file system for migration to a destination file system based upon a migration plan constructed for transforming one or more source file system objects from a source file context path and a source file type to a destination file context path and a destination file type as one or more migrated file system objects;

reformatting a logical structure of a source policy collection for the one or more source file system objects based upon the migration plan to create a destination policy collection for the one or more migrated file system objects for optimizing the destination file system, wherein the reformatting comprises:

de-duplicating policy entries within the source policy collection to create an equivalent set of policy statements for inclusion within the destination policy collection based on how an architecture of a destination filer hosting the destination file system applies policy entries to defined file system objects, wherein the de-duplicating groups multiple policy entries into a logically equivalent policy entry formatted according to a structure and syntax of how the destination file system applies the policy entries to defined file system objects; and

migrating, based upon the migration plan, the plurality of file system objects from the source file system to the destination file system as migrated file system objects which includes the one or more migrated file system objects.

16. The non-transitory computer-readable medium of claim 15 , wherein the operations comprise:

executing a walker to evaluate resources of a source filer hosting the source file system to identify the plurality of file system objects.

17. The non-transitory computer-readable medium of claim 16 , wherein the operations comprise:

executing the walker to identify information regarding types of the plurality of file system objects.

18. The non-transitory computer-readable medium of claim 16 , wherein a first file system object of the plurality of file system objects comprises a container.

19. A computer system comprising:

a memory that stores a set of instructions; and

a processor that executes the instructions to:

identify a plurality of file system objects of a source file system for migration to a destination file system based upon a migration plan constructed for transforming one or more source file system objects from a source file context path and a source file type to a destination file context path and a destination file type as one or more migrated file system objects; and

reformat a logical structure of a source policy collection for the one or more source file system objects based upon the migration plan to create a destination policy collection for the one or more migrated file system objects for optimizing the destination file system, wherein the reformatting comprises:

de-duplicate policy entries within the source policy collection to create an equivalent set of policy statements for inclusion within the destination policy collection based on how an architecture of a destination filer hosting the destination file system applies policy entries to defined file system objects, wherein the de-duplicating groups multiple policy entries into a logically equivalent policy entry formatted according to a structure and syntax of how the destination file system applies the policy entries to defined file system objects; and

migrate, based upon the migration plan, the plurality of file system objects from the source file system to the destination file system as migrated file system objects which includes the one or more migrated file system objects.

20. The computer system of claim 19 , wherein a first file system object of the plurality of file system objects comprises a container.
