Error upgrading ZCM 10.3.1 to 11.2

Hello,

I brief description of my environment:

- 5 Primary Servers, on Windows 2008 Sp2 x64
- 1 Dedicated SQL server 2005 SP4
- ZCM 10.3.1

I'm upgrading my environment from ZCM 10.3.1 to 11.2. I followed these steps:

- Upgrade SQL Server to 2008 R2 SP1
- Start the upgrade process to ZCM 11.2 on one of my primary servers. All seems Ok, but at the statge Upgrading Packages, 98% I get an error.

I check the system-update.log and check this error:
