The Snom version 10.1.x is a major firmware update with many new features. Some of the improvements require configuration changes. See below for the most relevant changes which you should be aware of for a smooth migration.
This section can apply to SIP over TLS, HTTPS as well as LDAPs
For security reasons in version 10.1.x the TLS server authentication is enabled and is not possible to switch it off, if you are planning to upgrade your phones you should make sure that:

Since version 10.1.27.0 the full notation of substring filters can be used and some additional filters are available. Another main change on the LDAP behaviour is that the partial_lookup setting isn't anymore used for the LDAP lookup, you should define the proper search filter instead.
Another example, the following filter:
will perform a query search LDAP objects containing the number into the telephoneNumber, Mobile or ipPhone attributes, Eg.: if the phone receives a call from the number 123 the LDAP query filter will be: (|(telephoneNumber=*123*)(Mobile=*123*)(ipPhone=*123*))
See more information and examples here.
Version 10.x currently has a known issue: when "Initial query" is off, the LDAP search can in some cases return error "No final answer from LDAP server for request 2". This issue is currently being worked on (internal ID SAP-3441). If you face this issue, please enable "Initial query" as workaround, then inform Snom Support by opening a new ticket under helpdesk.snom.com .
The fix for this issue is available as of firmware version 10.1.41.1
If you are using LDAPS, you might need additional configuration, Please read carefully section "TLS Server authentication" above.
Starting with version 10 you can now define different name and number filters during the call lookup or the address book search, the settings are described as follow:
