1. A method of generating a repository template of a repository of data for a storage area network management tool, the repository defined to hold data describing storage area network elements and configurations, the method comprising: updating a configuration file to include current configuration data for a first repository, wherein the configuration file includes specifications for a set of schemas defining at least one repository structure; using configuration data from the configuration file to access the first repository currently stored on a host; removing any schemas and data currently stored by the first repository; creating a set of new schemas for the first repository according to the specifications from the configuration file; copying seed data to the host, wherein the seed data defines initial repository information; initializing the set of new schemas with the seed data; upon initializing the set of new schemas, generating a repository template from the set of new schemas and the seed data, the repository template defined for creating one or more repositories to hold storage area network data; creating a second repository from the repository template, wherein the second repository includes the seed data and the set of new schemas; establishing a test environment based on the repository template; wherein establishing the test environment includes: (i) exporting each schema in the set of new schemas into the test environment; (ii) replacing the seed data in each exported schema with data from at least one live storage area network (SAN); (iii) upon determining that each exported new schema properly handles data from the live SAN, indicating, in the test environment, that the second repository is acceptable; loading a prior version of the repository onto the host; comparing the schemas of the prior version of the repository with the schemas of the second repository to determine any differences; and creating at least one script that, when executed on a repository based on the prior version of the repository, will upgrade schemas according to the set of new schemas in the second repository; via the test environment, receiving a correction of at least one schema in the set of new schemas, wherein receiving the correction includes: upon determining that at least one exported schema does not properly handle the data from the live SAN: resolving at least one incompatibility between at least one portion of data from the live SAN and an exported new schema.
