EHP7 Upgrade - NZDM (Near Zero Down Time) has anyone upgrade with this option

$

Hi

 

I would like to know if anyone has an experience to upgrade by using SUM and using the ZDM option.

 

I am doing my QA system upgrade to EHP4 to EHP7 / Windows 2008/SQL env. I have never used this option before. I would like to know how it's going to use. Do I have to manually bring down the shadow instance ? Currently, I am stuck in a execution phase and it's not moving further.

I started a /nCRR_Control process manually. Now there are no tables in the server list but it still running. It's been running since past 3 days.

It says " The replication of recorded changes is currently active"

 

 

"More than 95% of recorded changes are transferred. You can start the downtime now or at a later point in time depending on your schedule. Keep monitoring the transfer until the start of the downtime."

 

 

1) I would like to know how long Do I need to wait?

2) Why I can't move the phase further ?

3) What needs to be done in order to complete the upgrade.

 

4) The following background job is still active since Thursday

RSUPG_ISU_CRR

DDIC          Active   01.11.2014 00:37:06         216.3692) since I have

manually started the T-code /nCRR_CONTROL data transfer

 

5) Do I need to stop the data transfer process or in other word to stop

the /nCRR_Control it shows the message below:

 

 

6) Do I need to cancel this job and stop /nCRR_Control transaction.

then restart the instance and start the Execution Phase . I have done

that and it failed.

 

I need to know what will be the next step ? how should I proceed.

 

My SUM is SUM10 SP11

 

 

Currently I am stuck in Execution Phase both Original and Shadow instances are up.

 

I am getting these errors:

CRRLAST.LOG

1EETQ399 Last error code set is: Single errors (code <= 8) found in logfile 'RSCRRLST.ELG'
