Migrate Oracle NVARCHAR2/NCLOB Column to VARCHAR2/CLOB
When the current Oracle instance supports UTF-8 characters, this tool will change all existing
NVARCHAR2/NCLOB columns to VARCHAR2/CLOB.
- The process creates a temporary VARCHAR2 column, populates it, drops the original column, renames the temporary column.
- The drop/rename process will not happen until the code detects that there are no more changes to make.
Technically it is relatively safe to run the migration process on an database instance where CopyStorm may be running.
