There is any way to change partition scheme from left to right without dropping Table in production.

Hi All,

There is any way to change partition scheme from left to right without dropping Table in production.

I am doing testing on Table Partitioning & requirement is to do partition (3 Partitions Only) on DateTime column & then load the data to (IN table which is empty) & then Switch in to Main (MAIN Table). Table is having 307 millions records. Currently I have done left Partition on the table & want to change to Right to test the Merging of last boundary value& Split Latest Boundary & then Switch in.

While do so for Left Partition Merge is taking hell of time & All tables getting locked on this schema till merge is done. Why this is happening bez

Partition -1 (All Data around 300 Millions)

Partition-2  (Latest-1 Data 6 Millions)

Partition-3 (Latest Data 6 Millions)

Partition-4 (Empty)

With Left partition When trying to merge Partition-1 It is moving (All Data around 300 Millions) to Partition-2 & taking lots of Time.

I want to Test same thing with RIGHT Partition but I don't want to Drop the Partition Table (Left Partition) Just want to change the Function/Schema from Left to RIGHT. There is any way to do this.?

Same questions I got below but no ans:
