How to extend 1 partition

Hello,

I'm using a Macbook Pro with 1TB SSD storage.

On this drive I created 2 partitions. 1 with macOS Sierra and 1 with an older version.

I need this older version for some old softwares that are not compatible with the newest versions. I'm running out of storage on my macOS Sierra partition and want to use some storage of the other partition.

EG:

- Partition 1 = 500GB - 40GB free

- Partition 2 = 500GB - 300GB free

Newest version of macOS is on Macintosh HD 2 and want to extend it with space of Macintosh HD.

Can this be done? And if so... how?

this is my partition table:
