Appendix A: Migration from i75 to i62
A.1 General
When migrating from i75 to i62 VoWiFi Handsets, or having a site with mixed population of
VoWiFi Handsets, there are certain SW versions that need to be compatible for a working
installation. Below follows information of the needed SW versions for i62 and i75 VoWiFi
Handsets.
i62 VoWiFi Handset:
i62 SW VoIP

IMS3 UPAC Unite CM

IMS3 UPAC Unite CM

PDM
1.7.12 v.7HF15 x.x 2.00 2.03 x.x.x
All SW versions of higher number than mentio
ned above will work.
A.2 VoIP Gateway
If a VoIP gateway is needed the SW version must be v.7HF15 or later for support of the i62.
If a site is mixed with both i62 and i75 VoWiFi Handsets the SW version of the i75 must be
upgraded to 1.7.12 or later to be compatible with the needed VoIP Gateway version.
A.3 UPAC
UPAC only partly supports i62 as it does not have support for license handling or security
certificates. It is therefore recommended to upgrade UPAC to UniteCM, but for a sales trial at
an existing site where UPAC is already installed it is possible to have i62 installed for tests
(with handset licenses pre-installed).
Please note that UPAC is phased out and no s
upport/NCRs wil
l be considered in an i62
installation.
A.4 SysPDM/IMS-IP
When i62 replace i75 on a site SysPDM must be replaced by an IMS3 (or from March 2011
with IMS3). A backup file of SysPDM can be imported directly to the IMS3 and the sysPDM
license can be reused in IMS3. Note that messaging will not work via this module.
The IMS3 SW version for installations with i62 must be 2.72 or later.
Also the IMS-IP must be replaced by the IMS3. It is easiest to have a single IMS3 with
integrated SysPDM functional
ity, but if required for performance or in order to reuse the
SysPDM license, it is also possible to have one IMS3 replacing SysPDM and another IMS3
replacing IMS-IP. It is not recommended to combine IMS3 with IMS-IP even if it is
theoretically possible. Note also that IMS-IP license cannot be reused in IMS3.
