Hi @dnelson,
You can reinstall only OpenERP. But whatever the new configurations you have done in ERP will be lost. Please run the below commands to reinstall.
bahmni -i local stop
yum remove -y bahmni-erp
psql -Upostgres -c "drop database if exists openerp;"
yum install -y bahmni-erp
bahmni -i local start
Please clear the entries in markers table in openerp if you face any sync issues from MRS to ERP.
psql -Upostgres openerp -c "delete from markers"
