<p dir="ltr">I'm not, sure I completely understand your questions but I'll attempt to answer based on my understanding.</p>
<p dir="ltr">Yes, you can pre-config devices and users in CCM prior to migration. If they are Cisco IP phones, you'll need the MAC address and model of the phone at a minimum.</p>
<p dir="ltr">If they are non Cisco IP phones, you'll need to pre configure 3rd party sip devices (which is a different license requirement than a Cisco IP phone).</p>
<p dir="ltr">Place the preconfigured dial plan that isnt migrated yet (on CCM), in a temp. partition that the already migrated phones cannot access. As you migrate, change that partition using BAT, to the correct partition for the portion of phones you migrated.</p>
