In preparation for an upcoming project it was time to try out the vCenter Server Migration Tool for 6.0 (vCenter Server 6 U2M). I started with reading the vSphere Migration Guide and Release Notes to find out what the prerequisites are and if any known issues are reported.

vSphere Migration Guide

Release Notes

In the release notes I found the following known issue.

Release Notes Known Issue - Syslog and Dump Collector

In the vCenter Server Windows 5.5 the Syslog and Dump Collector are extra components you could deploy but in the vCenter Server Appliance 6.x the Syslog and Dump Collector are integrated in the appliance.

The pictures below show the difference in the vSphere Web Client. The left picture shows the vCenter Server Windows 5.5 with Syslog and Dump Collector and the right picture shows the vCenter Server Appliance 6.0 with the integrated Syslog and Dump Collector.

As you can see there are no more items for the Syslog and Dump Collector in the vSphere Web Client.

When you migrate from the vCenter Server 5.5 Windows to vCenter Server Appliance 6.0 and you have the Syslog and/or Dump Collector installed and configured as integrated with vCenter Server these items will still exist in the Web Client and will show an error even after configuring the services.

According to the release notes there is no workaround. The only way the avoid this issue is to uninstall the Syslog and/or Dump Collector before migrating to the vCenter Server Appliance.

As mentioned earlier in this post, this only happens when the Syslog and Dump Collector are configured as integrated with vCenter Server. If you have deployed them as standalone instances this issue does not occur.
