[389-users] How to shrink cn=changelog db

[Picture Book]

Setting nsslapd-changelogmaxage to shorter time will not automatically shrink cn=changelog db.

Is it ok to recreate cn=changelog db by:

1. turn off retro changelog plugin
2. restart DS
3. delete cn=changelog database
4. restart DS
5. enable cn=changelog, set nsslapd-changelogmaxage 
6. restart DS

Thanks.
