I restarted the background-upgrade process and got this:

RNING: Background upgrades pending. Please run nxdbmgr background-upgrade when possible.
[jaustin@jaustin systems]$ nxdbmgr background-upgrade
NetXMS Database Manager Version 3.3.285 Build 3.3-285-gfe2e9b646f (UNICODE)

Running background upgrade procedure for version 33.6
Converting table idata_sc_default

So apparently the upgrade process can't handle a resume, as it breaks on the tables that have already been migrated. (It had already dropped successful tables.)

I manually completed the inserts from the remaining tables using ON CONFLICT DO NOTHING, and dropped the remaining v33_5 tables.

However, the same problem exists -- I can't complete the upgrade because the v33_5 tables no longer exist.

if you already migrated and dropped temporary tables you should clear pending background update indicator by executing query

UPDATE metadata SET var_value='' WHERE var_name='PendingOnlineUpgrades';

Best regards,
Victor
