How to move the data from H2 database to another database ?

[PerennialDevOps]

We are running Bamboo Server 6.1 in production and it is currently running with the embedded H2 database. Seeing the critical condition and the risks of running with the H2 database, we want to move the database to another DBMS, say MSSQL Server. 

Can someone direct me on how to proceed with this process ? Also, will it also backup the database if I take the Export and import it in the new Bamboo instance with an external MSSQL database ?

You are on right path for production setup. H2 is never recommended for that.

On first part of your question,

• The migration is straight forward.
  • Backup old Bamboo instance.
  • Stop old Bamboo instance
  • Install new Bamboo instance,
  • Start new Bamboo instance,
  • In setup wizard (make sure you don't use any of the old directory)
    • Select DB type you want to use
    • Select import option (to import data from old Bamboo instance)
  • Once done, restart and re-index new instance.
• You can follow this guide - https://confluence.atlassian.com/bamboo/moving-your-bamboo-data-to-a-different-database-289277250.html

On second part of your question,

• Backup,
  • You can use existing backup strategy
  • But I personally recommend, (this is what I do)
    • Backup SQL DB
    • Backup Home (especially artifacts directory)
  • This link is great for automating your backup - https://confluence.atlassian.com/bamkb/automating-bamboo-backup-operations-702715390.html

Thanks @DPKJ , can you kindly elaborate more on 

• Backup SQL DB
• How to backup current H2 DB ? Or the same is exported alongwith other data when I do Overview > System > Export.

By "Backup SQL DB" I mean using database specific utility to backup your database.

In your case for "MSSQL" Microsoft gives these options - https://docs.microsoft.com/en-us/sql/relational-databases/backup-restore/create-a-full-database-backup-sql-server?view=sql-server-2017

Your DBA might be aware of this.

@DPKJ Got it. Thanks.

Need your comment at last on, 

• How to backup current H2 DB ? Or the same is exported alongwith other data when I do Overview > System > Export.

[DPKJ]

Yes, you are correct DB backup is part of System Export. And hence, you don’t need to backup internal DB separately.
