<h2>Purpose</h2>

<p>This procedure describes how you can move either the Talk-family BTS
or the UltraSite/MetroSite BTS to a new segment of its own.</p>

<h2>Before you start</h2>

<p>If you want to move the UltraSite or MetroSite BTS that
has the BCCH TRX, you must first delete the BCCH channel because moving a
BTS containing a BCCH TRX is not allowed. All BTSs of the old segment must
also be in the locked state.</p>
