How to go to command prompt of bitbucket to configure the setting

[Mythrayi Balaji]

Hi Team,

We are facing issue while we tried to  import a repository from GIT lab to Bitbucket.

Since the size of the repository  is huge we cannot import the same through HTTP url .

We are not sure on how to import using SSH.

When surfed in the internet we found 2 configuration to be added

client_max_body_size 0;

proxy_request_buffering off;

But we are not sure on how to open the command prompt of bitbucket and and add the above two configuration.

Team, can you please guide the steps on how and in 
which path we can find command prompt and execute the above two setting commands??

The documents you have found that tell you to use these configurations should tell you where to add them (to what config file on the Bitbucket server)
