You can create new empty template, open data collection configuration for existing one, select DCIs you want to copy to new template, right-click, select "Copy to other node...", and select new template object as destination.

You can modify templates using nxshell and Python scripts. Info about nxshell can be found here: http://wiki.netxms.org/wiki/Using_nxshell_to_automate_bulk_operations, and Java API documentation is here: https://www.netxms.org/documentation/javadoc/latest/ (you call Java API from nxshell script).

I've recreate specific template per maker. What is the best way to duplicate a template ? Is it clever to export / do modification or merge modification /re-import ?

Is there some info on how we can modify templates by scripts ?

%{script:SelectOID}

instead of actual OID in template, and create script called [n]SelectOID[/b] in script library, which will return correct OID for given node. This script will have $node variable set, so it can get any information about the node.

For example:

if ($node->snmpOID like ".1.3.6.1.4.1.11.*")
   return ".1.3.6.1.4.1.11.2.3.4.5.6.7.8.0";
return return ".1.3.6.1.2.1.1.1.0";

Not sure if this will be easier then configuring separate templates...

what is the best to do this ?

Last solution may be to export one template,  modify the xml, and then re-import ? (not really clean, and don't know how the object IDs will match ?)

Custom attributes are attached to the object. Template only handles data collection configuration, custom attributes will not be copied. Custom attributes was designed to store object-specific attributes, and often used by integration tools or scripts. For data collection it is usually enough to create different templates for different vendors/models.

Custom Attributes created in a template are not "visible" from script created in another one.

I've create a CA in HP template MaxMemoryOID = .1.3.6.1.4.1.11.2.14.11.5.1.1.2.1.1.1.5.1
I've bind a HP switch to this template.

And in a generic Switch template, I've create a dummy DCI to get SNMP value :

sub main()
{
	trace(1,"Get CA=" . GetCustomAttribute($node, "MaxMemoryOID"));
	snmp = CreateSNMPTransport($node);
	return SNMPGetValue(snmp, GetCustomAttribute($node, "MaxMemoryOID"));
}

If CA is manually defined in the node : it works, if it is inheritated from first template : value is NULL.

Any idea to overcome this ?
