 +===== Conversion to BIGINT for two tables in Runtime =====
 +Due to a problem where the auto_increment values reached their maximum, we convert two of the columns to BIGINT, instead of INT. The two tables affected are:
 +  * nagios_hostchecks - this stores host check results
 +  * snmptrapexceptions - used for SNMP trap exceptions
 +
 +To speed up the upgrade, the upgrade process will truncate both tables if conversion to BIGINT is needed.
 +
 +You may want to consider altering table definition for those tables manually if you want to keep the data.
 +
 +In any case, you may want to check that [[opsview-core:mysql#mysql_tuning|mysql]] has been tuned because we have reports that this upgrade step takes a long time if not enough memory is allocated to Mysql.
