Hi David,

LDAP schema dictates how the attribute specific tables are built. Once after the tables are initialized, just replacing the schema files will not help in updating the table/column definitions. We must do a synch procedure which will update not just the schema but get correct db2 table/column definitions and in addition update any corresponding data. And this must be done offline, when ldap server processes is stopped.

There are two methods you can use:

1. Use idsdbback on Master1, transfer the entire backup folder from Master1 to Master2, then idsdbrestore(along with -r flag) on Master2. 
   
   
2. Alternatively, follow the sequence as in this tech note:
   https://www.ibm.com/support/pages/node/394231
   
   

If you need more detailed instructions, please proceed to open a case with "Directory server" support.
