How to migrate master and keep slave in sync?

Hi, we have a 2.4.21 master on Solaris and a syncrepl 2.4.21 slave on Linux, and need to migrate the master to a new platform (Linux) and new version (2.4.21). Of course we need that the syncrepl slave (not managed by us) keeps in sync with the new master.

Given that the ip, ports and certificates of the new master will not change, would it be enough to do the following? 1) stop the "old" 2.4.21/Solaris master 2) import its contents (via slapcat and slapadd) into the "new" 2.4.23/Linux (stopped) master 3) start the new 2.4.23/Linux master

Thank you very much, Stefano
