Migrate from talend 7.3 to 8

[a_farina]

Hi,
we need to migrate a Talend 7.3 environment to a new infrastructure, and at the same time upgrade to Talend 8.
The database for the TAC will still be MySQL, but installed on a new server.

What is the correct procedure to migrate the TAC database?
Should we take a dump of the Talend 7.3 database, restore it on the new MySQL server, and then connect to it via the Talend Administration Center (TAC) web interface and perform the upgrade from there?

Thankyou

Hello,

https://help.qlik.com/talend/en-US/migration-upgrade-guide/8.0/upgrading-administration-database

Upgrading the administration database

This section describes how to upgrade the Talend Administration Center database. Note you can skip the database backup, for data security reasons or other important circumstances.

Kind regards

Hi,
yes, we have already reviewed the official guide, but it doesn't mention moving the database to a new server — it assumes the old database is kept as-is.
In our case, we are moving to a new, empty database on a different server.

Hello,

The TAC WebApp will use the TAC DB defined in the file configuration.properties (can be defined via the TAC DBCONFIG page too .. )

So, if you want to use a TAC DB located on another machine , yes : the "old" TAC DB should be exported and imported in the "new" Database, then "connect" the TAC WebApp to this "new" TAC DB

Kind regards

NOTE : export the "old" TAC DB when the TAC WebApp is stopped in order to avoid any inconsistancies in the TAC DB .
