Following are some additional considerations when changing from a Single-tier model to a Multi-tier model:

• You must move or copy any of your customized or application image files which were stored on the Data/Application Server IFS to the Web Server IFS.
• If you are using SSI (Server Side Includes), remember that these are URL dependent and may require files to be moved to the IFS on the Web Server.
• If you are using validation lists for standard authentication, these lists must be created on the Web Server.
