Hi, This bug https://issues.apache.org/jira/browse/CLOUDSTACK-6603 [Upgrade]DB Exception while Autoscale monitoring after upgrading from 4.3 to 4.4] got introduced by the feature of "Autoscaling without netscaler"
A new column "last_interval" got added to autoscale_vmgroups table by this commit (dc151115be3e922933ea26ab1507eb6469a91e11). Schema of autoscale_vmgroups table got changed in wrong version of schema file cause the upgrade failed. Instead of adding schema change to the upgrade path file it was added to setup/db/db/schema-40to410.sql file. It should be added to schema43to44 upgrade path. Because of this issues, upgrade from 4.3 to 4.4 and 4.3 to 4.4 will fail. @Tuna, can you please have a look at your commit and fix it. @Daan, if this issue CLOUDSTACK-6603 is not fixed, upgrades from 4.2 to 4.4 and 4.3 to 4.4 will fail. As 4.4 feature freeze had happened long back, Am not sure whether we can change db schema now in 4.4 branch Thanks Rajesh Battala
