Dear all, I have a 4-way multi-master openldap servers running in version 2.4.11. Let's say the servers name are A, B, C, D. I have another 4-way multi-master openldap servers running in version 2.4.40. Let's say the servers name are W,X,Y,Z. What's the proper procedure of migrating the data from servers A,B,C,D to W,X,Y,Z ? My procedure is as follows :- Export data from server A using slapcat command.- Delete the first 6 lines of the ldif files (the lines contains the contextCSN).- Shutdown the process slapd in servers W,X,Y,Z and remove all the openldap data files under /usr/local/var/openldap-data.- Import the ldif files to server W, then start the slapd process in server W.- Export the ldif files from server W.- Import the ldif files to server X,Y,Z respectively.- Start the slapd process in X,Y,Z. What I observe is that all four servers then has 100% CPU and never drop back to idle ? So, is there anything I do wrong ? Thanks
