This is an update of the blog entry of June 9th, 2015 (KW 24).
The Combined Upgrade & Unicode Conversion procedure (SAP Note 928729 – Combined Upgrade & Unicode Conversion (CU&UC)) can reduce the total downtime of both operations by already performing some Unicode Conversion preparations in parallel to the upgrade. The subsequent Unicode Conversion will benefit from these preparations.
If your SAP system had been installed with a single Latin-1 code page, you can now reduce the downtime even more by performing the In-place CPC on IBM i procedure within the Unicode Conversion phase. SAP Note 800791 – IBM i: In-place Code Page Conversion ASCII to Unicode and the attached documentation of the In-place CPC on IBM i procedure (ASCII_Unicode_CPC.pdf, version 2.3 and higher) have been adjusted, so that the In-place CPC procedure can now be used together with the Combined Upgrade & Unicode Conversion. The CU&UC and the In-place CPC fit perfectly together to minimize your code page conversion downtime.
Of course, the In-place CPC on IBM i procedure still supports the normal Unicode Conversion (SAP Note 1051576 – Conversion of Single Code Page Systems to Unicode) as before.
