ML Skill deployment failed after migration
ML Skill deployment might fail after migrating to 2022.10
After upgrading to AI Center 2022.10.0 and moving to external storage, making a skill created in 2022.4 public will fail.
This issue was fixed in 2022.10.2. To fix this, upgrade to a newer version.
For 2022.10.0, run this script to fix the issue.
Recreating databases
If there is an issue with your databases, you can recreate them from scratch directly post-installation.
You can do this by running an SQL command to drop all the DBs and recreate them as follows:
USE [master]
ALTER DATABASE [AutomationSuite_AICenter] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
DROP DATABASE [AutomationSuite_AICenter]
CREATE DATABASE [AutomationSuite_AICenter]
GO
USE [master]
ALTER DATABASE [AutomationSuite_AICenter] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
DROP DATABASE [AutomationSuite_AICenter]
CREATE DATABASE [AutomationSuite_AICenter]
GO
