It is recommended that you go through every line in the command procedure and understand the<br />

conversion. Some of the important points that you need <strong>to</strong> verify in the command procedure are:<br />

• Naming conventions used in the conversion as it can differ from what is exepected<br />

• Errors in converting the SBK policy<br />

• Possible ABS Policy consolidation<br />

B.2.4.3.5 Consolidating ABS Policy Objects –<br />

Be<strong>for</strong>e executing the command procedures <strong>to</strong> create the ABS Policy objects, you should try <strong>to</strong><br />

consolidate S<strong>to</strong>rage Classes and Execution Environments. You can also combine the Save<br />

requests if warranted by the intended policy. In some cases, breaking a Save request in<strong>to</strong> several<br />

sub-requests is better <strong>for</strong> various reasons like reducing the nightly backup time, simplifying an<br />

overall backup policy, or backing up different objects at different intervals.<br />

Attempts are not made <strong>to</strong> consolidate the S<strong>to</strong>rage Classes and Execution Environments, or <strong>to</strong><br />

overlay the Save requests <strong>for</strong> more optimum per<strong>for</strong>mance.<br />

Consolidating S<strong>to</strong>rage Classes –<br />

Consolidating the S<strong>to</strong>rage Classes is done by comparing the parameters of pairs of S<strong>to</strong>rage<br />

Classes. For each pair of S<strong>to</strong>rage Class, you can determine whether they can be combined or left<br />

unchanged. Note that in all cases, you can decide that one or the other parameter is correct <strong>for</strong><br />

both and consolidate based upon that decision. See Table B–5, (S<strong>to</strong>rage Class (<strong>Archive</strong>) Parameter)<br />

<strong>to</strong> view the list of S<strong>to</strong>rage Class parameters and their matching criteria.<br />
