Upgrading from Version 10 to Version 11

Overview

The structure of the operating database has changed in Fusion Metadata Registry (FMR) version 11 making it incompatible with version 10. An existing FMR 10 installation cannot be directly upgraded to version 11, and a version 11 database cannot be used with version 10 of FMR.

If you attempt to start an FMR instance using a version 10 database it will fail to start. We recommend using an empty database and loading structures into it. To upgrade from 10 to 11 please follow the steps below.

If you wish to preserve structures and settings from a version 10 database please see the section below titled: Migrating Structural Metadata History and Settings

Backing Up an Existing Fusion Metadata Registry

To create a file containing all of the structural metadata within your Registry, please perform the following:

• In your current version 10.X FMR, navigate to the Export Structures / Bulk Actions page.
• Click on the green "Download all structures" button
• In the modal that appears ensure that the format is specied as Fusion-JSON. You may choose to download as a Zip file so that the generated film is smaller in size.
• Download the structures and store them safely as these will be used to upload in your Fusion Registry version 11

You may now stop the Apache Tomcat running this instance of FMR.

Starting the Version 11 Fusion Metadata Registry

If you attempt to start FMR against a version 10 database, the Registry will detect this and will halt the startup process. It is highly recommended to use an empty database.

To start FMR version 11

• Deploy the war file into your existing Java WebServer (e.g. Apache Tomcat).
• Start the Java Web Server and wait for the FMR to fully deploy
• Using your browser navigate to the front page of FMR.
• Step 1 of the install wizard will be shown. Supply the details of your new database.
• On Step 2 of the install wizard set the server location and the root account.
• Finish the install wizard.

You will now have a running FMR (although with no content) that has an associated database for persistance of your structures and settings

Login and Upload Structures

You should login to the Fusion Registry and upload the structure file you obtained from FMR version 10.

• Login to the FMR
• Navigate to the front page
• Using the "Load Structures" control found at the top right of the page, load the structure file
• Wait - the time taken to load will depend on the size of the structures present in your file.
• Ensure that the structures have loaded by looking at individual pages or the Export Structures / Bulk Actions page to see an overview.

In the unlikely event that there are any issues loading the structures, please check the Web Server log files and also the "Server Integrity" page (located in the left-hand menu bar) which reports any structures that break the Registry Integrity. If you need help, please contact Metadata Technology for further support.

Migrating Structural Metadata History and Settings

When migrating from FMR 10 to version 11 it is simpler to migrate metadata via an exported SDMX JSON file (as described earlier in the page). However it is possible to preserve the following information from FMR 10:

• All metadata structures
• The history for individual structures
• Many of the settings
• Some of the audits

The instructions are detailed below. Within these instructions the database that is used for FMR 10 will be refered to as FMR_10_DB and the database used for FMR 11 as FMR_11_DB. Of course your database names will be different. FMR_11_DB should be an empty database.

For information about the purpose of each table in FMR, please refer to this page .

Instructions

The following instructions will take you through the process of creating a SQL file of the appropriate information from your FMR 10 database, modifying the SQL file's content, loading this file back in to your database and finally making some final adjustments to the tables before attempting to start FMR 11. In this scenario FMR 11 will not be starting against an empty database.

Create a SQL file of database tables

Using the database tool of your choice (for example SQLYog) navigate to the FMR_10_DB. Create a file which is the SQL Dump of the table Structure and Data for the following tables:

• registry_audit
• registry_maintainable_sdmx
• registry_maintainables
• registry_settings
• registry_settings_dv
• registry_settings_ser
• sdmx_backup
• sdmx_transaction
• sdmx_transaction_item
• tx_backup

How you perform this is down to the tool and the database you are using. For MySQL databases, the tool SqlYog has a convenient way to perform this. Via the menu option: Database -> Backup/Export -> Backup Table(s) as SQL Dump... within the modal that appears, select only the tables listed above. Ensure the radio button "Structure and Data" is checked. And save this to a single file.

The file produced may be quite large - the size depends on the content of your Registry.

Edit the SQL file

3. View the generated file in an editor of your choice. SqlYog lists 3 occurrences of the FMR_10_DB. These are:

• On line 3: in a comment
• On line 15: in a "CREATE DATABASE"
• On line 17: in a "USE" statement

Change all of these so that they refer to the database you are going to use for FMR_11 then save the file again.

Load the SQL file into your database

4. Against the database FMR_11_DB. Load in the file. Using SqlYog use the menu option: Database -> Import -> Execute SQL script. In the modal that appears select the file and click "Execute"
5. If it errors, please let me know
6. Once the import finishes your FMR_11_DB will contain the 10 tables listed above.

Make final modifications to the data

Run the following MySql script in a window. NOTE: change the first line to the actual name of your FMR_11_DB:

USE `FMR_11_DB`;

DELETE FROM registry_settings WHERE NAME = 'installed.version';
DELETE FROM registry_settings WHERE NAME = 'registry.url';
DELETE FROM registry_settings WHERE NAME LIKE 'EXCEL_TEMPLATE_PWD_%';
COMMIT;

Then

ALTER TABLE sdmx_transaction_item MODIFY COLUMN id VARCHAR(255) NOT NULL; COMMIT;

Start FMR 11

7. Start the Tomcat that will be running FR11. This should direct to step 1 of the Install Wizard.
8. On step 1 specify the details for database FMR_11_DB.
9. The Registry should now show install page 2. If it doesn't something has gone wrong.
10. On install wizard step 2 enter the password for the root user. Complete the install wizard.
11. The front page of the Regsitry should be shown. Remember that security prevents viewing of unauthorized structures. Either use Fusion Security Manager to give permission to public or log on.
12. Check that the structures are present. Check that individual structures have history
