Hi
As is well known, you
must patch Exchange 2007 to the very latest Service Pack and Update Rollup before you attempt to do anything with Exchange 2013.
According to your description, I suggest you should check the rangeUpper value by using ADSI Edit . If the value was 14625. This indicates
your schema is at Exchange 2007 SP3.
Here is the article for your reference: https://supertekboy.com/2014/05/01/check-exchange-schema-objects-adsi-edit/
Also you could re-install the patches in the following links .
Please download and install these patches from here:
Exchange Server 2007 Service Pack 3: https://www.microsoft.com/en-gb/download/details.aspx?id=24111
Exchange Server 2007 SP3 Update Rollup 10 : https://www.microsoft.com/en-us/download/details.aspx?id=36708
Hope its helpful to you .
Best Regards,
David
