I am trying to migrate  iRedmail from my old version ( 0.8.87) to the latest version on Ubuntu 12.04.

As part of this  I imported ldap entries with a ldif import. Now  I am trying to update
the LDAP attributes version by version on the new server.

The new server is Ubuntu 20.04 . When I run the  command after making changes according to
LDAP entries, I am getting the following error:

/update# python updateLDAPValues_087_to_090.py
Traceback (most recent call last):
  File "updateLDAPValues_087_to_090.py", line 20, in <module>
    print >> sys.stderr, "* Connecting to LDAP server: %s" % uri
TypeError: unsupported operand type(s) for >>: 'builtin_function_or_method' and '_io.TextIOWr

Please let me know what exactly went wrog.

Regards
Sandeep
