Can I convert parquet files to Delta?

[User16826992666]

I am already storing my data as parquet files and have registered them as a table in Databricks. If I want to convert the table to be a Delta table, do I have to do a full read of the data and rewrite it in the Delta format?

We can convert Parquet table to Delta using below command

CONVERT TO DELTA <table_name>

CONVERT TO DELTA parquet.<location>

its better to provide table name so that metastore also gets updated, also it would be good idea to avoid update/insert new data while converting to Delta.
