Poblem importing DB full backup

[Jettaman]

I have solved thus:
This is the correct:
"CREATE TABLE t1 (
  ts TIMESTAMP(6) DEFAULT CURRENT_TIMESTAMP(6) ON UPDATE CURRENT_TIMESTAMP(6)
);"
This is not permitted:

CREATE TABLE t1 (
  ts TIMESTAMP(6) DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP(3)
);

Thank you very much.

Hello cfreire, 
The t1 table you are talking about is not apart of sentoras default installation. This table may be in your database because you installed an old third party module or had this module installed for many years with no updates or support. We are trying to get a record or old modules that need to be updated before upgrade as soon as we can. Thank you for finding this and reporting it to us.
