Error in upgrading DNG from CLM6.0.6.1 to ELM 7.0.2

     Am getting error in upgrading DNG from CLM 6.0.6.1 to ELM 7.0.2.

Applied iFix010 on ELM 7.0.2 and for CLM 6.0.6.1 we have used iFix023.

We have ran the 

"JazzInstallDir/Sever>upgrade\rm\rm_upgrade.bat -oldApplicationHome "D:\CLM_Installs\IBM\CLM_6.0.6.1_Liberty\IBM\JazzTeamServer6061\server\conf" -newJTSHome "D:\CLM_Installs\IBM\ELM_7.0.2_Liberty\IBM\JazzTeamServer702\server\conf" -jtsRepositoryUrl https://hostname.org.net:9443/jts -adminUserId ** -adminPassword ** "

The error which we are getting is as below.

On DNG when we ran the upgrade command, In Export link Validity data command it says as below. <o:p> </o:p>

<o:p>   </o:p>

CRJAZ1356E  The repotools command could not connect to the following server ‘https://hostname.org.net:9443/jts’ <o:p> </o:p>

<o:p>  (Same URL which we used in upgrade command) </o:p>

The rm upgrade failed at step 1. <o:p> </o:p>

<o:p>   </o:p> We followed the jazz.net link

<o:p> </o:p>

<o:p>   </o:p>

“https://jazz.net/wiki/bin/view/Deployment/MigratingTheRequirementsManagementLinkValidityData%22 <o:p> </o:p>

<o:p>   </o:p>

But still we were unable to cross the step. <o:p> </o:p>

Could anyone help on this.

Thanks,
