Migration

[Vivek Manpuria (Vivek)]

I was going over the Migration Guide at https://docs.killbill.io/latest/migration_guide. 

In order to transfer the accounts and subscriptions from an existing system to killbill postgreSQL, can the data be inserted directly into the killbill database after which can we restart killbill?

I tried it out and it worked for an account. However I got an error, Null Pointer Exception when calling the Get Account Bundles and Get Account Blocking States API probably, because I did not enter data into all the tables. I will try a bit more.

Thank you,

Vivek

Hi Vivek,

By inserting data into DB, do you mean to directly copy over the data from a different system db to Kill Bill db? Are the columns in the source/destination matching? I would suggest to give it a try in your Kill Bill test environment first with a few accounts and take it forward accordingly.

Hi Karan,

Yes, I was planning to create a subscription by inserting records in the kill bill database tables. The columns do not match but we have all the data that kill bill requires because I am able to migrate an account using the KillBill APIs. I found it to be risky because of the number of tables that are involved and also because some of fields contain serialized objects and KillBill generated user tokens.

Thank you,

Vivek

Hi Vivek,

Yes that is correct. There is a lot going on in the core system, so its always better to let the system do the work.
