I currently do have version 2.3. When I try to replicate the database between the two servers, it seems that the version 2.6 server does not accept the replication request from the version 2.3 server. Is this not supported then ?</P> Fri, 21 Feb 2020 17:56:45 GMT gvandenbogaert 2020-02-21T17:56:45Z Database replication problems between ACS v2.3 and ACS v2.6 https://community.cisco.com/t5/network-access-control/database-replication-problems-between-acs-v2-3-and-acs-v2-6/m-p/5104#M10136 <P>I want to upgrade my Cisco Secure ACS to version 2.6.

See &#147;Important Notes: at <A class="jive-link-custom" href="http://www.cisco.com/univercd/cc/td/doc/product/access/acs_soft/csacs4nt/csnt26/usergd26/ch4.htm" target="_blank">http://www.cisco.com/univercd/cc/td/doc/product/access/acs_soft/csacs4nt/csnt26/usergd26/ch4.htm</A> With the current database in place, the installation of the new version will update it and create a new one. One caveat: If a backup was performed prior to upgrading (a good idea), the backup will not be compatible with the new version of ACS. To restore this backup, you would have to go back to the previous version to fully restore the backup. A final note, csutil -d (dump.txt) is compatible, but is limited to user and group information only. Hope this helps.</P></BODY></HTML> Tue, 17 Apr 2001 21:50:12 GMT https://community.cisco.com/t5/network-access-control/database-replication-problems-between-acs-v2-3-and-acs-v2-6/m-p/5105#M10137 mmellet 2001-04-17T21:50:12Z
