This is Version 2 of the COP file named as "elm_LicenseDef_9_1_v2.cop.sgn", which
provides the means to apply a new License Definition file to 9.1 ELM software.
License Definition files provide the means to update ELM software for supporting new
product instances, license tags, license versions, etc. without the need to update the
current software.
This version 2 of the COP file has been released with Collaboration Solution Release 11.0
allowing ELM 9.* to support 10.x and 11.x Products.
NOTE: This COP file should not be used with License Manager software at or greater
than version 10.0, which contains a GUI interface for applying new License
Definition files to the system. Version 10.0 and greater has been re-branded as
Cisco Prime License Manager.
