Upgrade 6.2 > 8.10 failure

Hi all,

i'messing around with the upgrade from 6.21 to 8.1.

When i run through the install Gui the upgrade fails with "Installation terminated due to error(s) on exporting old database.

In the logfile omnimigrate_.....log everything looks good, until i see the following lines at the end:

[....]
StartServices()

	Sys()

			C:\OmniBack\bin/omnisv -start 

		OpenFileForWriting()

					 file=C:\OmniBack\tmp\tmp_omnimigrate_vjmXD_cmd_stdout
					 file=C:/OmniBack/tmp/tmp_omnimigrate_vjmXD_cmd_stdout
		OpenFileForWriting time = 0 s

		OpenFileForWriting()

					 file=C:\OmniBack\tmp\tmp_omnimigrate_kNS1E_cmd_stderr
					 file=C:/OmniBack/tmp/tmp_omnimigrate_kNS1E_cmd_stderr
		OpenFileForWriting time = 0 s

				 stdOut=C:/OmniBack/tmp/tmp_omnimigrate_vjmXD_cmd_stdout

					 Cannot start "crs" service, system error:
					[1053] The service did not respond to the start or control request in a timely fashion. 
		ReadStdOut time = 0 s

	Sys time = 26 s

	Die()

			msg='C:\OmniBack\bin/omnisv -start ' returns:
			Cannot start "crs" service, system error: [1053] The service did not respond to the start or control request in a timely fashion. 

			err=SYS_FAILED

So there is a problem with starting the services in time, which is strange, because i never had issues with this (but i never stop/start them with the omnisv command).

Server is W2008R2 Std. running on VMware, VM with 4 CPUs, 4GB, low cpu and disk load on Hardware. Antivirus disabled for install.

What can i do about this?

thanks & cheers
