<div style="font-family: Calibri,sans-serif; font-size: 11pt;">First - 10.5 SU1 should be your target release unless you have a compelling reason to go to 10.x.
<br>
<br>
Generally it is a non issue when dealing with those parameters. CUCM should by default be the higher priority of enterprise and service parameters. When dealing with conflicts most people I have worked with choose to retain the CUCM parameters without exception.
<br>
<br>
Taking note of the parameters isn't a bad thing but like the document says it'll be overwritten and you'll have to make the choice after the upgrade to change things or not. At that point your changing parameters for the whole CUCM cluster and not just IM&P.
<br>
<br>
Think of IM&P as simply a supplemental service to the cluster and not a cluster of its own.<br>

<div>I am planning an upgrade from a CUCM and CUPS 8x to CUCM and IM&P 10x and I came across this passage in the CUCM 10.0(1) Upgrade Guide, and I was wondering if anyone has experience to share on this topic?</div>

With the merging of Cisco Unified Communications Manager and IM and Presence Service, enterprise and service parameters are now shared between nodes in a cluster. As such, both types of nodes use the same settings for enterprise and cluster-wide parameters.
You need to be aware that not all parameter settings are retained during an upgrade to Release 10.0(1). All enterprise parameters and cluster-wide service parameters that are common to both Cisco Unified Communications Manager and IM and Presence Service retain
the value specified on Cisco Unified Communications Manager only, with one exception. The User Assignment Mode parameter is the only enterprise parameter that is retained during upgrade. Service parameters that apply to IM and Presence only are retained after
an upgrade.<br>

Cisco recommends that before you begin an upgrade, you make a note of parameter settings and evaluate the best settings for the combined cluster. This will allow you to easily configure those settings after the upgrade is complete.</blockquote>
