Hi Kasper,
99% of all builds are classified as "Restricted" which yours will most likely be going forward. Here is
a description of the differences;
Unrestricted Export Support
The restricted US export classification on Cisco Unified CM meant that governmental and military customers in many countries could not employ Unified CM in their networks.
In addition to the delay inherent in obtaining export licenses, products classified as restricted by the Department of Commerce (DoC) carry a requirement to allow US government representatives to demand on-site inspections at any time to confirm that the product is being used in accordance with its licensed purpose. This post-shipment verification (PSV) is unacceptable to many customers.
Additionally, some foreign countries maintain import restrictions which prohibited Unified CM from being available to customers in those countries. Both US export and foreign import issues stem from Unified CM support for strong encryption of signaling and media.
Unrestricted Classification
Because Cisco has obtained an unrestricted classification from the DoC for a version of Unified CM, beginning with Unified CM 7.1(5), both restricted and unrestricted versions of Unified CM will be released in parallel.
Limitations
Signaling and media encryption is permanently disabled in the unrestricted version, but remains unchanged in the restricted version.
Migration from the unrestricted version to the restricted version is not supported.
Note 
No impact exists to other security features such as HTTP(s), SSH, password encryption and authentication (for example, SIP digest authentication), mechanisms used by unrestricted Unified CM clients such as JTAPI, TSP, encryption of SNMP traffic, encryption of data related to database that is done by using IPSEC and IMS on the server side.
The communication between CTL client and provider remains encrypted.

So this will be the file;
UCSInstall_UCOS_7.1.5.33900-10.sgn.iso

Hi Kasper,
Sorry for the vague "time" reference. Your procedure is just fine so I don't mean to
throw any question that way. When doing the actual "switch-version" at the end
of the upgrade process just make sure that the Pub is fully "up" before starting the
"switch-version" on the Sub. Check that all the services have come up, that you have
gui and cli access etc. It just takes longer than we think....that's all I meant
As for the phones, if you happen to be running any older firmware versions like pre-8-3-3
you will want to be careful. There are some two step firmware upgrade requirements due to
the fact that the new CUCM 7.1(5) will be upgrading the firmware to newer versions. For example
the 7945's will be moving to sccp.9-0-2SR1.cop.sgn and you can't move to that version if you are
@ pre-8-3-3 as shown in this note from the release notes;
Firmware Upgrade Issues for SCCP
Note For all SCCP firmware upgrades from firmware release versions earlier than 8.3(3) to version 9.0(2)SR1 or greater, you must first upgrade your firmware to version 8.3(3). Once you have upgraded to version 8.3(3), you can upgrade your IP Phone to version 9.0(2)SR1 or later.
If you are running newer firmware versions you should be good to go. As a general rule we do all
the firmware upgrades as a separate step prior to the upgrade window just to mitigate the risks
and to minimize the downtime.
Cheers!
Rob
