Server Migrations no longer require ordering a Hardware Migration SKU as long as you are deploying a User
Connect Licensing release (i.e. 7.1(5) or higher). For reference the old rules for Device License Units releases
(5.0(1) to 7.1(4)) are listed below (Table 14).
Table 13. Server Migrations
Upgrading via…
Hardware Migration SKU Required?
UCSS
Only if migrating to a release prior to 7.1(5) or 8.0(1)
CUCM SW Upgrade SKU
Only if upgrading by <2 Major Releases and to a release prior to 7.1(5) or 8.0(1)
Re-purchase new CUCM Major Release
NO
Major releases are the first digit of the version number. E.g., a major release changes if you upgrade from 4.0 to 6.0
or later. A major release does not change if you upgrade from 6.0 to 6.1.
Examples of “<2 Major Releases” are 3.3 > 4.3, 4.2>4.3, 5.1>6.0, 6.1(2) > 6.1(3), 6.0>6.1, 6.0>7.1.
Examples:
●
Hardware Migration SKU is required for:
◦ Migrate to different server, no software upgrade
◦ Migrate to different server, upgrade via UCSS
◦ Migrate to different server, upgrade 6.0 to 6.1 via upgrade SKU
◦ Migrate to different server, upgrade 6.0 to 7.1 via upgrade SKU
●
Hardware Migration SKU is not required for:
◦ Any upgrade to 7.1(5) or 8.0(1) or higher
◦ Migration from MCS 7800 to UC on UCS
◦ Migrate to different server, upgrade 5.0 to 7.1 via upgrade SKU or repurchase of 7.1
◦ Migrate to different server, upgrade 4.0 to 6.0 or later via upgrade SKU or repurchase of 6.0 or later.
◦ Keeping same server, no software upgrade
◦ Keeping same server, upgrade 6.0 to 6.1 or later
◦ Keeping same server, upgrade 6.0 to 7.0
◦ Keeping same server, upgrade 5.0 to 7.0
To determine which Hardware Migration SKU you need, do the following:
a. Order your replacement server as if it is a new system - see instructions in Cisco Unified Communications
Manager and Media Convergence Server sections. Pay special attention to “hardware add-ons” and
“component changes”.
b. Get prefix of Hardware Migration SKU for your version of Cisco Unified Communications Manager.
c. Get suffix of Hardware Migration SKU for your “from” (existing) and “to” (replacement) Server Classes.
d. Order the Hardware Migration SKU corresponding to the prefix and suffix.
These steps are described in more detail below.
b. Get prefix of Hardware Migration SKU for your version of Cisco Unified Communications Manager
