<h1 class="topictitle1">Common methods of estimating installation time</h1>
|
|
<div><p>Use the following information to understand the different ways
|
|
to estimate installation time. </p>
|
|
<div class="p">The following list contains the
|
|
most common methods of estimating your installation time for an upgrade.
|
|
<ul><li>Base your estimate on the installation time of a previous release. If
|
|
the system configuration and load remain similar, you can use the installation
|
|
time of a previous release on this system <em>as the start</em> of your estimate.
|
|
If you rely on only the installation time of the previous release, your estimate
|
|
might not be accurate. <p>This method is
|
|
not accurate if many data conversions occur during the installation process.
|
|
If you are skipping a release level, generally the time is longer. Be sure
|
|
to add information for conversions that occur in the release you are skipping
|
|
and for the new release.</p>
|
|
</li>
|
|
<li>Base your estimate on the installation time for a similar system. If your
|
|
enterprise has multiple systems, you can record the actual time to install
|
|
the new release on one system. You can use this to estimate the time that
|
|
is needed to install the new release on a system with a similar configuration
|
|
and load. Of course, you cannot use this method until you complete the installation
|
|
on the first system.</li>
|
|
<li>Estimate time using a formula. You can use the information in the following
|
|
sections to estimate how long it will take to install this release on your
|
|
system. Keep in mind that the number at which you arrive will vary from your
|
|
actual installation time because of the variables that affect installation
|
|
time.</li>
|
|
<li>Combine one or more of the methods that are listed above.</li>
|
|
