Rosetta 7.1 Service Pack - Special instructions for Solr upgrade and rollback

Background

Rosetta versions 5.4 - 7.0 use Solr version 6.5.
In Rosetta 7.1, Solr was upgraded to version 7.3.1.

Special instructions for service pack installation (and rollback)

During Rosetta 7.1 service pack installation:
A backup of the current Solr index from each IDX server is created under $op_dir/indexes_backup_solr_6.5.0/<IDX server hostname>/
This means that installation might take longer than usual and that enough disk space must be available under $op_dir (i.e. Operational Shared Storage)

In case Rosetta version 7.1 is rolled back to the previously installed Rosetta version (using util sp in the Linux command line interface):
Solr indexing will not work - in this scenario Rosetta's features/screens that depends on Solr (e.g. 'Search for Objects' screen, SRU, etc) will not work as well.
There are two options to resolve this:

1. Re-index the whole repository (Rosetta Administration → General → Index Status → Click 'Reindex Full Repository' from both 'Permanent Index' and 'Operational index' tabs)
2. Manually copy the Solr index from $op_dir/indexes_backup_solr_6.5.0/  to Solr index path** in each IDX role server of the environment.
   ** Out-of-the-box Solr index path is: /exlibris/dps/d4_1/profile/solr/data/
        To get current Solr index path, run:

   grep dps.storage.idx $dps_system/conf/global.properties|cut -d= -f2
