Check also the following parameters …

1. The following parameters are still valid but usually they should not be used because the default values in the kernel are typically the most suitable ones (please check the SAP Notes in brackets). So if these profile parameters are used in your system check if the reason for introducing them is still valid.
abap/collation/icu_sortkey_factor
abap/collation/strxfrm_min_factor
abap/locale_ctype
i18n/bidi/logical_number_printing (see SAP Note 618988 for details)
rsts/ccc/cache07
rsts/ccc/cachesize (see SAP Note 99699 for details)
rsts/ccc/max_sapcode?
rscp/ccc/protect

2. The following parameter should not be removed but updated with the results from report RSCPINST as described in SAP Note 42305.
