Anacreo, Alec

Thany you for your help, but I am not sure that help . May I was not 100% clear 
with my english, I apologize that.

Some comments  :
>>>>If you're doing a straight migration, in my experience, from the same

  From OS view , I will make a straight migration (Solaris 8 to Solaris 10) , 
but not from the HW , old platform  Sun V480 to Sun M4000, same 
robotics-libraries and VTL  to switch to the new HW as well new  hostname/ip ...

>>etc... Then stop NetWorker, copy /nsr (Make sure you don't harm your old data 
>>for a rollback),
In the past , I alreday made a migration from an old platform to a new HW (not 
the same hostname and ip, etc  ), according the procedure form the DRG 
Documentation ( for example  bakup all indexes from whole groups, and restore 
with mmrecov, ans so one at end nsrck -L7, etc.. ) , not only transfer the /nsr 
 to the new sysrem .

Procedure much more complex as described in the documentation DRG (desaster 
recovery guide) . I wrote  in relation with  the customer a  detailed  
documentation what we did, not in english... It was ok ,except the fact there 
is , in some file /nsr/res from the new server , still the old name server...I 
must solve that but it is not urgent... if anybody had an idea .. it concerns 
"localhost" configuration files.. i dont know how to remove 100% the old name 
server in  the new ..but it is not the purpose of this email. The old one is 
completly remove from the network.. 

 
>>>start NetWorker, delete all your Jukebox and Device info... (yes its a pain 
>>>to remove them from your media pools), add them in. 
   We have installed from scratch into th new HW the networker 7.4.4 , not yet 
licensed , will be done later...

As  wroten before : 


>>>- there is a module for Informix , which write Logs to a special device 
>>>called /nsr_file_dev0 , a file system on a partition. 
I guess that is possible to do a simple copy of these files to the new 
server...but i would like to be sure.. 

This not in /nsr , that are  the backup of the log files in Informix... I 
guessed That I can copy after the stop of the source  Networker 
to the target networker. But I am not  sure...

>> there are some storage nodes configured , which are NAS with datamovers. I

In my previous migration  of an other networker server , it was only a storage 
node , which was the networker server itself..
I hope that the mmrecover will transfer  right the config

As the first step the test of  recovering of all indexes group and the 
bootstrap of the source networker server was ok..
 
Thanks
