Abstract

A method and system for migrating content on a network. In one method embodiment, the present invention accesses a directory having a network address. A business rule is created and a directory is scripted based on the business rule. Next, a content switch automatically directs future access to the directory to a new environment based on the scripting, wherein the future access to the directory uses the same network address. In so doing, the migration of content on a network is greatly simplified.

Claims

1. A system comprising:

a memory unit for storing data including a current network address and a new network address; and

a content switch configured to;

read application-level information in a packet header, wherein the application-level information corresponds to Open Systems Interconnection data connectivity model layer 7, and wherein the content switch is further configured to receive a request to access the current network address, wherein the request comprises the packet header;

read the application-level information provided in the packet header;

look-up the new network address from the memory unit including a directory;

input the directory into a spreadsheet template;

create a business rule and parse the directory using scripting based on the business rule;

initially automatically direct the request to access the current network address to the new network address based on the application-level information; and

subsequently automatically redirect subsequent requests to access the current network address to the new network address based on the scripting if no error occurs corresponding to the initial automatic directing, else automatically redirect the subsequent requests to access the directory to the current network address if an error occurs during the initial automatic directing.

2. The system of claim 1 wherein the spreadsheet template comprises switch compliant files.

3. The system of claim 2 wherein the switch compliant files are in extensible markup language (XML) format.

4. The system of claim 3 wherein the switch compliant files are uploaded to the content switch via scripts.

5. The system of claim 1 wherein the new network address is associated with data that resides on a server distinct from a server maintaining data associated with the current network address.

6. The system of claim 1 wherein the new network address is associated with data that resides on a same server as data associated with the current network address.

7. The system of claim 1 wherein the new network address is associated with data that partially resides on a new server distinct from a server maintaining data associated with the current network address.

8. A non-transitory computer-readable medium having instructions stored thereon, wherein when the instructions are executed by at least one device, the instructions are configured to cause the device to:

receive a packet including a request to access a current network address;

reformat a migration file comprising a plurality of network entries associated with one or more current network addresses including the requested current network address, and further associated with one or more new network addresses corresponding to the one or more current network addresses, wherein the migration file is reformatted using a switch compliant language;

update a first switch compliant file with the reformatted migration file comprising the plurality of network entries to create a second switch compliant file comprising a new network address corresponding to the requested current network address; and

direct the request for access to the current network address to the new network address based on switching instructions provided in the second switch compliant file, wherein if an error occurs associated with the switching instructions in the second switch compliant file, then restore the first switch compliant file and redirect a subsequent request to access the current network address according to switching instructions provided in the first switch compliant file.

9. The non-transitory computer-readable medium of claim 8 wherein the first and second switch compliant files comprise an extensible markup language (XML) format.

10. The non-transitory computer-readable medium of claim 8 wherein the new network address is associated with data that resides on a new server distinct from a server maintaining data associated with the current network address.

11. The non-transitory computer-readable medium of claim 8 wherein the new network address is associated with data that resides on a same server as data associated with the current network address.

12. The non-transitory computer-readable medium of claim 8 wherein the new network address corresponds with data that is partially stored on a new server distinct from a server maintaining data corresponding with the current network address.

13. A method for migrating content on a network comprising:

storing data including a current network address and a new network address;

receiving a packet including a request to access the current network address;

reading application-level information in a header of the packet, wherein the application-level information corresponds to Open Systems Interconnection data connectivity model layer 7;

accessing a database containing at least one directory;

inputting the directory into a spreadsheet template;

creating a business rule and scripting the database based on the business rule; and

automatically redirecting future access to the directory to a new environment associated with the new network address based on the scripting if no error occurs corresponding to the redirecting, else automatically directing future access to the directory to an old environment associated with the current network address if an error occurs during redirecting.

14. The method of claim 13 further comprising building the spreadsheet template using simple tables parsed with scripts to create switch compliant files.

15. The method of claim 14 further comprising inputting a directory status into the spreadsheet template, wherein the directory status includes one or more of the following:

a directory location, a current rule owner, an operational status and a future location of the directory.

16. The method of claim 15 wherein the new environment is on a separate subnet from the old environment and wherein the new environment may be associated with a different virtual local area network (VLAN) from the old environment.

17. The method of claim 13 further comprising determining whether to redirect access to the new environment based on one or more errors associated with one or more previous requests to access particular content residing in the old environment.

18. The method of claim 13 wherein the new environment is on a same server as the old environment.

19. The method of claim 13 wherein the new environment is partially stored on a new server distinct from a server maintaining the old environment and the same servers as an old environment.

20. The method of claim 13 further comprising seamlessly delivering content and applications from the old environment and the new environment using a same virtual Internet protocols.
