How to rename the aws lambda function without changing anything in it

Earlier my function in serverless was:

functions:
    fun:
        handler: file.handler
        name: ${opt:stage, self:provider.stage}-lambda-fun
        environment: ${file(env.yml):${self:provider.stage}.lambda-fun}
        timeout : 180
        memorySize : 1024

I want to change fun with some meaningful name, So I changes it as:

Earlier my function in serverless was:

functions:
    my-fun:
        handler: file.handler
        name: ${opt:stage, self:provider.stage}-lambda-fun
        environment: ${file(env.yml):${self:provider.stage}.lambda-fun}
        timeout : 180
        memorySize : 1024

Now When I deployed this function through serverless, Got the below error:

An error occurred while provisioning your stack: my-funLogGroup - /aws/lambda/lambda-fun already exists

Please help me What I can do more to do this.

It's not the exact same issue but this github issue gives an alternative soulution: Cannot rename Lambda functions #108

I commented the function definition I wanted to rename and the resources with references to it, then sls deploy , uncommented and sls deploy again.

The problem with this is that the first deploy will delete the function so you have to take into account this down time.

Try removing the stack first using serverless remove and then redeploy.
