Migrate data from V4R4 ,V4R5, or V5R1 to V5R4

i5/OS V5R4 does not support direct upgrades from V4R4, V4R5, or V5R1. If you want to migrate these releases to V5R4, you can follow either of the following procedures:

• Upgrade from V4R4, V4R5, or V5R1 to an interim release
• Save the database library and install V5R4

When you upgrade from V4R4 to any later release, you should be aware of the following issues:

• V4R4 and earlier releases of Directory Server did not take time zones into account when creating time stamp entries. Beginning with V4R5, the time zone is used in all additions and modifications to the directory. Therefore, if you upgrade data from V4R4 or earlier, Directory Server adjusts existing createtimestamp and modifytimestamp attributes to reflect the correct time zone. It does this by subtracting the time zone that is currently defined on the iSeries system from the time stamps that are stored in the directory. Note that if the current time zone is not the same time zone that was active when the entries were originally created or modified, the new time stamp values will not reflect the original time zone.
• If you are upgrading data from V4R4 or earlier, be aware that the directory data will require approximately twice as much storage space than it required previously. This is because in V4R4 or earlier versions, Directory Server supported only the IA5 character set and saved data in ccsid 37 (single byte format). Directory Server supports the full ISO 10646 character set. After you upgrade, you should start your server once to migrate existing data before importing new data. If you try to import data before starting the server once and you do not have enough authority, the import might fail.
