Abstract

A method, computer program product, and system for data replication between software versions is described. A method may comprise determining if a first item created in a first software version includes data native to a second item in a second software version. The method may further comprise, if the first item created in the first software version includes data native to the second item in the second software version, storing the data native to the second item in the second software version as native data. The method may also comprise, if the first item created in the first software version is missing required data based upon, at least in part, the second item in the second software version, storing a default value for the missing required data as native data.

Claims

1. A method comprising:

determining, via at least one of a client electronic device and a server computer, if a first item created in a first software version includes data native to a second item in a second software version;

if the first item created in the first software version includes data native to the second item in the second software version, storing, via at least one of the client electronic device and the server computer, the data native to the second item in the second software version as native data;

if the first item created in the first software version is missing required data based upon, at least in part, the second item in the second software version, storing, via at least one of the client electronic device and the server computer, a default value for the missing required data as native data; and

if the first item created in the first software version includes data that is non-native to the second item in the second software version, storing, via at least one of the client electronic device and the server computer, the data non-native to the second item in the second software version as auxiliary data.

2. The method of claim 1, further comprising at least one of:

sending the first item from a first computing environment running the first software version to a second computing environment running the second software version; and

loading the first item after the first software version is upgraded to the second software version in the same computing environment.

3. The method of claim 1, further comprising:

sending the native data and the auxiliary data to a downstream computing environment when the second item in the second software version is sent to the downstream computing environment.

4. The method of claim 1, wherein at least one of the native data, the required data, and the non-native data includes at least one field.

5. The method of claim 1, further comprising:

storing a field as native data wherein the required data includes the field and the default value corresponds to the field.

6. The method of claim 4, wherein the at least one field was added to a schema in the second software version.

7. The method of claim 1, further comprising:

loading all required data into memory if the second item in the second software version is used.

8. The method of claim 1, wherein the non-native data is stored in its original format.

9. The method of claim 1, wherein the auxiliary data is stored persistently.

10. A computer program product residing on a computer readable storage medium having a plurality of instructions stored thereon, which, when executed by a processor, cause the processor to perform operations comprising:

determining if a first item created in a first software version includes data native to a second item in a second software version;

if the first item created in the first software version includes data native to the second item in the second software version, storing the data native to the second item in the second software version as native data;

if the first item created in the first software version is missing required data based upon, at least in part, the second item in the second software version, storing a default value for the missing required data as native data; and

if the first item created in the first software version includes data that is non-native to the second item in the second software version, storing the data non-native to the second item in the second software version as auxiliary data.

11. The computer program product of claim 10, further comprising instructions for at least one of:

sending the first item from a first computing environment running the first software version to a second computing environment running the second software version; and

loading the first item after the first software version is upgraded to the second software version in the same computing environment.

12. The computer program product of claim 10, further comprising instructions for:

sending the native data and the auxiliary data to a downstream computing environment when the second item in the second software version is sent to the downstream computing environment.

13. The computer program product of claim 10, wherein at least one of the native data, the required data, and the non-native data includes at least one field.

14. The computer program product of claim 10, further comprising instructions for:

storing a field as native data wherein the required data includes the field and the default value corresponds to the field.

15. The computer program product of claim 13, wherein the at least one field was added to a schema in the second software version.

16. The computer program product of claim 10, further comprising instructions for:

loading all required data into memory if the second item in the second software version is used.

17. The computer program product of claim 10, wherein the non-native data is stored in its original format.

18. The computer program product of claim 10, wherein the auxiliary data is stored persistently.

19. A computing system comprising:

at least one processor;

at least one memory architecture coupled with the at least one processor;

a first software module executed on the at least one processor and the at least one memory architecture, wherein the first software module is configured to, determine if a first item created in a first software version includes data native to a second item in a second software version;

a second software module executed on the at least one processor and the at least one memory architecture, wherein the second software module is configured to, if the first item created in the first software version includes data native to the second item in the second software version, store the data native to the second item in the second software version as native data; and

a third software module executed on the at least one processor and the at least one memory architecture, wherein the third software module is configured to, if the first item created in the first software version is missing required data based upon, at least in part, the second item in the second software version, store a default value for the missing required data as native data; and

a fourth software module executed on the at least one processor and the at least one memory architecture, wherein the fourth software module is configured to, if the first item created in the first software version includes data that is non-native to the second item in the second software version, store the data non-native to the second item in the second software version as auxiliary data.

20. The computing system of claim 19, further comprising at least one of:

a fifth software module executed on the at least one processor and the at least one memory architecture, wherein the fifth software module is configured to send the first item from a first computing environment running the first software version to a second computing environment running the second software version; and
