Synchronization error when setting up AX2012 R3

This will be a quick post on an error I had when setting up a fresh AX2012 R3 installation. I was getting a bit ahead of myself and got stuck with an error when synchronizing the database.

And to help search engines find this post, the error in clear text:

Cannot create a record in Inheritance relation (SysInheritanceRelations). MainTableId: 12345.
The record already exists. 

The error is due to the fact that I didn't restart the AOS after compiling the application. Lesson is; don't rush and do it the right way the first time.
Furthermore, if you DO get stuck, try do a quick search on Life Cycle Services for a solution:

Restarted the AOS and continued the installation.

Delete Company in AX 2009 using SQL

One of the potential tasks when upgrading to a new version of Dynamics AX (like from AX2009 to AX2012) is getting rid of obsolete companies. Microsoft shared a SQL for this a few years back. I enhanced it a little bit and added some additional statements.

Just one important remark - DO NOT RUN THIS AGAINST AX2012!

In the interest of sharing, here it is:
