Data Merging

[Raggs]

Hello Team, 

Greetings for the Day..!

I have a question and need help on some urgent requirement.

We have  data upto June-2020  in SQL and same hassbeen connected with Qlikview.

Now, we have changed DB from SQL to Oracle and we have data from July-2020 to till date in Oracle DB.

We should merge the old data with New data... 

Can anyone help me to explain how to merge....

If the conversion has changes to the data structure or meaning of the data, a good idea would be to keep a QVD of the historical stuff and merge in the new data where needed.  you may want to migrate a portion of the active data.
