Summary0003308: Performing Full Upgrade of SymmetricDS Steps
DescriptionDear Sirs

We Currently Successfully Run SymmetricDS 3.7.2 between a PostgreSql Master to Sybase Target and it works very Well.

Recently my developers attempted to Upgrade to SymmetricDS 3.8.29 and it failed.

They Followed The Brief Instructions found in the Manual Under F.1 Full Upgrade.

However, I would like to understand if there are Any Steps in the Initial Startup of a Upgraded SymmetricDS.

They Did exactly the Steps 1 thru 7,

However when SymmetricDS Restarted (or was Started as we have normally Start it) We Ran into an issue because the version of Postgresql jdbc driver we used referred to a system level column that was removed in the Database System Table in Postgres v9, So we got all these Errors

[PostgreSqlDdlReader] [symmetric-engine-startup-0] Failed to read table: sym_node_identity. Error: ERROR: column t1.tgisconstraint does not exist

We figured out the issue, and upgraded the JDBC Driver and Re-Started again.

 I can See in the Logs that SymmetricDS attempts to alter the Sym_ Tables and Drop Some ..etc.

However I saw These Messages

2017-09-21 16:07:48,835 WARN [gras-001] [AseDdlBuilder] [symmetric-engine-startup-1] Data cannot be retained in table sym_node_communication because of the addition of the required column queue .

n,heartbeat_time,timezone_offset,batch_to_send_count,batch_in_error_count,created_at_node_id,deployment_type FROM DAOA001.dbo.sym_node

And Symmds would not start and work

So We Restored the 8.7.2 Software, and I dropped all sym_ Tables in Source/Target and BAsically Restarted from Scratch the installation

We Want to Try this Again (with the Proper JDBC Driver)

However, I would like to know what the Appropriate steps for Restart should be in order to Upgrade the Software/Sym schema without having to lose my existing configuration.

Please let me know

Thank you
Steps To ReproduceInstall any Inferior version of SymmetricDS and have it working operationally between 1 or more tables in a Source/Target Replication configuration

And then Perform the Steps listed within the Manual

When SymmetricDS is started after a major or minor software update, it will alter its database tables with any changes needed for that release.
F.1. Full Upgrade
For major releases and clean upgrades, copy old settings into a new installation using the following steps:

1.Stop the old SymmetricDS.
2.Backup the old SymmetricDS folder by renaming it.
3.Unzip the SymmetricDS distribution.
4.Copy old files from "engines" folder. (These files contain database connection information and engine settings.)
5.Copy old files from "conf" folder. (These files contain settings for ports, wrapper, and logging.) Check to see if any new changes need merged.
6.Copy old files from "security" folder. (These files contain keys for encryption.)
7.Restart SymmetricDS.

And Explain what needs to occur within the Database From a Restart Standpoint in order to maintain the Existing Configuration within the DAtabase (routers, channels, transform_tables, transform_columns, node_group_link, node_group, node, conflict) and have it Startup correctly in the Upgraded Version.
