[SR-Users] Questions about LCR module

I am trying to port our setup from kamailio 1.4.3 to 3.1.4 and I see huge differences on the LCR module. I have these main questions: 1- does lcr_id replaces the grp_id? 2- what happened to the fifo commands to add gws etc: lcr addgw <gw_name> <ip> <port> <scheme> <transport> <grp_id> <flags> <tag> <strip> ............... add a gateway with flags, tag and strip ............ ................(flags, tag, and strip are optional arguments) ..... lcr rmgw <gw_name> .......................................................... ............... delete a gateway lcr addroute <prefix> <from> <grp_id> <prio> ................................. .............. add a route ( use '' to match anything in <from> ) lcr rmroute <prefix> <from> <grp_id> <prio> ................................. .............. delete a route 3- it looks like the kamctl fifo lcr reload can not be used anymore, instead I found that there is a sercmd command that can be used to "show" and "reload" only the lcr tables What would be the best way to use this module on this version? Any help/hint would be greatly appreciated. thank you fborot
