Oracle Solution for Error ora-01038

ORA-01038: cannot write database file version string with ORACLE version string

What triggered the Error:

Attempting to write datafile headers in an old format. The new format can not be used until after the database has been verified as being compatible with this software version.

What should we do to fix it:

Open the database to advance to the new file formats, then repeat the operation. If the operation is required before the database can be opened, then use the previous software release to do the operation.
