I successfully completed a migration from OrientDB to the H2 database by following the instructions provided here. Notably, step 4 states: Copy the produced nexus.mv.db file to your $data-dir/db directory. However, I found it unusual that there is no mention of removing the old OrientDB files. Currently, my $data-dir/db directory contains the following: drwxr-xr-x 2 root root 4096 Feb 3 2017 OSystem drwxr-xr-x 2 root root 4096 Aug 12 2019 accesslog drwxr-xr-x 2 root root 4096 Mar 3 15:56 analytics drwxr-xr-x 2 root root 4096 Jun 20 2019 audit drwxr-xr-x 2 root root 4096 Mar 3 15:56 component drwxr-xr-x 2 root root 4096 Mar 3 15:56 config -rw-r--r-- 1 root root 2 Mar 3 15:30 frozen.marker -rw-r--r-- 1 root root 93 Aug 8 2024 model.properties -rw-r--r-- 1 root root 19726336 Mar 4 01:45 nexus.mv.db drwxr-xr-x 2 root root 4096 Mar 3 15:56 security Am I correct in assuming that only the nexus.mv.db file is necessary? And everything else is no longer in use? Which of these files and directories can be safely removed?

Thank you, @mpiggott! Much appreciated. P.S.: If possible, please consider updating the documentation to include this valuable information.

You should be able to archive everything except the nexus.mv.db
