Some time ago, I wrote an article about upgrading a Microsoft SQL Server 2008 R2 Express edition to a full Standard Edition. Today I discovered that the transaction log of the vCenter Server database (in my homelab) has grown and needed some maintenance. VMware published KB 1003980 “Troubleshooting transaction logs on a Microsoft SQL database server” on this subject. However It is not my intention to go for a Simple recovery Model. So I decided to create a Maintenance Plan. After creating a Maintenance Plan, I discovered that it is not possible to modify an existing Maintenance Plan. There is an Modify option, but it just does not work.
