[389-users] 3.1 version where i are ndexes ?

HI List 

I 'm testing a  new  389-DS version 3.1 i RH 9 installation, I followed the RH Doc for migration from  version 1.2.3 copy only content and user.ldif , I re-create my indexes with  dsconf but I can not find where are this new LMDB indexes files? ( Iin old 1.2.3 I used the default userroot , but I can not find such userroot db in  latest veersion ?)  

Do I need to create userroot directory before or after indexes creation ?

sslapd-db-home-directory: /var/lib/dirsrv/slapd-test/db

/var/lib/dirsrv/slapd-testl/db/
