Different suplementary services on IP Office 9.0 and 9.1 issue

Hi all,

We had build 2 sites using IP Trunk with voip setting in line sub type IP Office scn with in IP Office rel 9.0.0 829 with succesfull.

Now we buy 4 New IPO release 9.1.0.0 437 and want to join them using SCN to existing site above, but I can not find IP Office SCN in line sub type in this version, only none, H450, QSIG on dropdown menu.

my question:
[ol 1]
[li]what should I do to join all them without any issue, is different supplementary services ok ?, is different release ok on SCN ?[/li]
[/ol]
[ol 2]
[li]If any Issue, we have plan to recreate SDcard with IPO release 9.0.0. 829. How about all my license, are license OK..? we have essential editioan licesense and 3rd party ip endpoin, IP500 Voicem networking channel and avaya ip endpoin[/li]
