Before a migration from a server with custom hosting is initiated, the hosting description file is validated for errors. Once the validation is completed, a report is displayed listing all detected issues. Here is what the validation tool output may look like:
Hosting description file 'hosting-description.json' validation failed: - Customer 'Alex Smith': Required element 'login' is not specified - Subscription 'alex.tld', mailbox 'firstname.lastname@example.org': mailbox does not have valid domain name. Mailbox should be located under one of these domain names: 'alex.tld' - Subscription 'jsmith.tld': source document root '/var/www/vhosts/jjsmith.tld' specified in hosting description file does not exist on the source server 'myserver' (10.52.46.227)
If there are errors, the migration is aborted so that the hosting description file can be corrected before proceeding.
The file is validated successfully if all of the below are true:
- The hosting description file exists and is readable.
- The hosting description file is a valid YAML or JSON file.
- The hosting description file structure is valid (for example, ‘login’ and ‘password’ fields are supplied for every declared customer account).
- Certain conditions for the objects to be migrated are met (for example, every mailbox to be migrated belongs to a domain).
- All the files and directories to be migrated are present on the file system.
