Avi Migration Tool

Project Details: Avi migration tool is a Python package that can convert configurations from different load balancers (such as F5, NSX-T, and Netscaler) into Avi configurations. The converter takes input as configuration files from these load balancers and outputs Avi configuration in JSON format, which can be uploaded to the Avi Vantage Controller for migrating applications and settings.

There are two ways to input configurations:

• Command Line: Input configuration on the command line.

• Download from Source Box: Converter downloads the configuration and profile defaults from the source load balancer.

Upon successful run, the converter outputs the results in the output directory with the following contents:

• ConversionStatus.xlsx: Status of the conversion, an Excel file with each row representing configuration object and its migration status, and corresponding Avi configuration.

• Output.json: The output of the migrated configuration in Avi Vantage configuration JSON format. This configuration can be uploaded to the Avi Vantage controller.

• converter.log: Troubleshooting log for the Converter, useful for debugging and logging purposes.
