Abstract

Example methods and systems to validate integrity of data and one or more configurations in response to an upgrade in a virtualized computing environment are disclosed. One method may include preparing a first pre-upgrade backup file and a first post-upgrade backup file in response to a data plane upgrade of the virtualized computing environment and validating the integrity of data and one or more configurations based on the first pre-upgrade backup file and the first post-upgrade backup file before upgrading a control plane of the virtualized computing environment.

First claim

What is claimed is:

1. A method to validate integrity of data and one or more configurations in response to an upgrade in a virtualized computing environment, wherein the method comprises:
preparing a first pre-upgrade backup file and a first post-upgrade backup file in response to a data plane upgrade of the virtualized computing environment;
validating the integrity of data and one or more configurations based on the first pre-upgrade backup file and the first post-upgrade backup file before upgrading a control plane of the virtualized computing environment;
preparing a second pre-upgrade backup file and a second post-upgrade backup file in response to a control plane upgrade of the virtualized computing environment;
validating the integrity of data and one or more configurations based on the second pre-upgrade backup file and the second post-upgrade backup file before upgrading a management plane of the virtualized computing environment;
preparing a third pre-upgrade backup file and a third post-upgrade backup file in response to a management plane upgrade of the virtualized computing environment; and
validating the integrity of data and one or more configurations based on the third pre-upgrade backup file and the third post-upgrade backup file after upgrading the management plane of the virtualized computing environment.

2. The method of claim 1 , further comprising storing the first pre-upgrade backup file, the first post-upgrade backup file, the second pre-upgrade backup file, the second post-upgrade backup file, the third pre-upgrade backup file, and the third post-upgrade backup file in a physical backup server other than any node of the virtualized computing environment.

3. The method of claim 1 , in response to any data included in the first pre-upgrade backup file not corresponding to any data in the first post-upgrade backup file, further comprising determining that data is missed in response to the data plane upgrade and pausing to proceed the control plane upgrade.

4. The method of claim 3 , further comprising performing a first rollback operation to restore the virtualized computing environment back to a point before upgrading the data plane based on the first pre-upgrade backup file.

5. The method of claim 4 , wherein the rollback operation is in response to an input on a user interface of the virtualized computing environment.

6. The method of claim 1 , in response to any data included in the first pre-upgrade backup file corresponding to any data in the first post-upgrade backup file, further comprising proceeding to the control plane upgrade.

7. The method of claim 1 , in response to any data included in the first post-upgrade backup file not corresponding to any data in the first pre-upgrade backup file, further comprising determining that a new element is added in response to the data plane upgrade and proceeding to the control plane upgrade.

8. The method of claim 1 , in response to any data included in the second pre-upgrade backup file not corresponding to any data in the second post-upgrade backup file, further comprising determining that data is missed in response to the control plane upgrade, pausing to proceed the management plane upgrade, and performing a second rollback operation to restore the virtualized computing environment back to a point before upgrading the control plane based on the second pre-upgrade backup file or to a point before upgrading the data plane based on the first pre-upgrade backup file.

9. The method of claim 1 , in response to any data included in the third pre-upgrade backup file not corresponding to any data in the third post-upgrade backup file, further comprising determining that data is missed in response to the management plane upgrade and performing a third rollback operation to restore the virtualized computing environment back to a point before upgrading the management plane based on the third pre-upgrade backup file, to a point before upgrading the control plane based on the second pre-upgrade backup file, or to a point before upgrading the data plane based on the first pre-upgrade backup file.

10. A computer system configured to validate integrity of data and one or more configurations in response to an upgrade in a virtualized computing environment, wherein the computer system comprises:
a processor; and
a non-transitory computer-readable medium having stored thereon instructions that, in response to execution by the processor, cause the processor to:
prepare a first pre-upgrade backup file and a first post-upgrade backup file in response to a data plane upgrade of the virtualized computing environment;
validate the integrity of data and one or more configurations based on the first pre-upgrade backup file and the first post-upgrade backup file before upgrading a control plane of the virtualized computing environment;
prepare a second pre-upgrade backup file and a second post-upgrade backup file in response to a control plane upgrade of the virtualized computing environment;
validate the integrity of data and one or more configurations based on the second pre-upgrade backup file and the second post-upgrade backup file before upgrading a management plane of the virtualized computing environment;
prepare a third pre-upgrade backup file and a third post-upgrade backup file in response to a management plane upgrade of the virtualized computing environment; and
validate the integrity of data and one or more configurations based on the third pre-upgrade backup file and the third post-upgrade backup file after upgrading the management plane of the virtualized computing environment.

11. The computer system of claim 10 , wherein the non-transitory computer-readable medium having stored thereon additional instructions that, when executed by the processor, cause the processor to store the first pre-upgrade backup file, the first post-upgrade backup file, the second pre-upgrade backup file, the second post-upgrade backup file, the third pre-upgrade backup file, and the third post-upgrade backup file in a physical backup server other than any node of the virtualized computing environment.

12. The computer system of claim 10 , wherein the non-transitory computer-readable medium having stored thereon additional instructions that, when executed by the processor, cause the processor to, in response to any data included in the first pre-upgrade backup file not corresponding to any data in the first post-upgrade backup file, determine that data is missed in response to the data plane upgrade, pause to proceed the control plane upgrade, and perform a first rollback operation to restore the virtualized computing environment back to a point before upgrading the data plane based on the first pre-upgrade backup file.

13. The computer system of claim 12 , wherein the non-transitory computer-readable medium having stored thereon additional instructions that, when executed by the processor, cause the processor to receive an input on a user interface of another computer system.

14. The computer system of claim 10 , wherein the non-transitory computer-readable medium having stored thereon additional instructions that, when executed by the processor, cause the processor to, in response to any data included in the first pre-upgrade backup file corresponding to any data in the first post-upgrade backup file, proceed to the control plane upgrade.

15. The computer system of claim 10 , wherein the non-transitory computer-readable medium having stored thereon additional instructions that, when executed by the processor, cause the processor to, in response to any data included in the first
