Our mango server will not start as it seems it has reached its maximum data point limit. From the ma.log
ERROR 2018-11-16T15:54:42,888 (com.serotonin.m2m2.Main.main:138) - Error during initialization
com.serotonin.m2m2.LicenseViolatedException: You have reached the maximum number of data points permitted for your 'Free' license: 300
Is it possible to remove data points from the terminal or otherwise salvage the installation/database so we can prune it as required?
