Migration from Oracle 11.2 to 19 with export/import without char set conversion
Hello,
Currently my customer has Oracle 11.2 no patches SE charset: WE8ISO8859P1
We want to migrate to Oracle 18/19 charset: AL32UTF8 using export/import as we can effort to have few hours downtime.
The only problem which we have is with charset conversion.
I ran csscan:
csscan FULL=y FROMCHAR=WE8ISO8859P1 TOCHAR=AL32UTF8 LOG=instchkc CAPTURE=N PROCESS=1 ARRAY=1024000
and as a result I got many lossy conversions which leads to ca 40k rows to modify.
Currently we have not enough resources for this cleanup task so the question is can we migrate to Oracle 19 without such conversion?
