Hey,
Just add the necessary information to a csv file, set up the csv like this:
name, new-name
site2_xxx_xxx, site3_xxx_xxx
site2_xxx_yyy site3_xxx_yyy
site2_xxx_zzz, site3_xxx_zzz
and so on...
(Use quotation marks if the object names contain spaces)
Afterwards place the csv file on your SMS (or the management PC, which is used to access the SMS via the SmartConsole) and execute either
mgmt_cli set-host -b ./path/to/the/csv/file => locally on the SMS
or
mgmt_cli.exe -m <ip_of_SMS> set-host -b ./path/to/the/csv/file => from the client which has the SmartConsole installed, the mgmt_cli.exe can be found within the SmartConsole install directory. You can open it via cmd or PowerShell.
And that's basically it. If your SMS isn't the best regarding the hw itself (under 4GB of RAM) you will need to activate the API server first. This can be done via the SmartConsole itself or the cli ~ "api start". If you have 4GB+ of RAM it should be automatically enabled.
More information regarding the mentioned api command can be picked up here.
Hope that helps you
Regards,
Maik
