hi dear guys ; 
we have a big issue with 2 types hardware version switch of T2500-10TS.
we had been bought 2 type hrrdware version 1.0 & 2.0 as one model switch is T2500-10TS. 

following details of switches as below : 
Ver: 2.0 
T2500-10TS 
Firmware Version : 2.0.0 Build 20181022 Rel.38882(s)

Ver: 1.0
T2500-10TS
Firmware Version: 1.0.0 Build 20160725 Rel.63965(s)

now , i want to ask you , can we change Firmware Version from Ver 2.0 to Ver 1.0 , it is possible ??

if we can change it , so on all commands and features can modify same ver 1.0 
 for example : we didnt find  "switchport mode access" in ver 2.0 but there is in ver 1.0 
after this changing Firmware Version to ver 1.0  , does it change in all command such as "switchport mode access" , so have we this command ??
please tell me is it possible or not ???
 i think it deponds on ASIC chip that can support it , but i think it is not possible , and Firmware Version is sole for each switch.
