Upgrade Tridion 2009 SP1 CM Database to 2011 SP1

Question

When performing pre-upgrade check for content manager database from Tridion 2009 SP1 to 2011 SP1 I recieve the following error in manager and log files.

Any clues?

<TdmLog DateCreated="2012-04-19T10:20:26" ApplicationVersion="6.1.0.996">
<Event DateTime="2012-04-19T10:20:26" Id="0" Type="1">
    <ErrorCode>0</ErrorCode>

Nuno is right. ErrorCode 0 means no errors, so pre-upgrade was successfully performed and found no issues. If there will be any issue found by pre-upgrade check then you will get error message popup and error code won't be 0.
