Hector - thanks man.

Isaac  - we will need to add this to their current and new site. 

Chris, 
you're welcome. 
Isaac, can you please also install this Google Analytics code?

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-164155138-1"></script>
<script>
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'UA-164155138-1');
</script>

Hector - Thanks.

Chris  - Can you please ask them to provide SFTP access to their current website and wp-admin for their new website. Thanks.

Isaac  - working on this with client. 

Hector - I confirmed with Chris and he said that we need to add GTM, hookup forms etc only on new website and not on current website.

I have now added above GA and GTM code to client's new website.

Have also added client's new website credentials in the spreadsheet.

He also mentioned on client's current website we need to connect it with the Google search console. I have included you in that email thread. Let me know if you need my help in adding any verification code in their current website for it. Thanks.

Thank you for clearing that all up and taking care of it. 
Also for including me in the email. 
I will take care of the Google search console task. If I need your help adding the code for verification, I will let you know. 

Isaac  - we will probably need your help verifying the Google Search Console - can you let me know once complete so I can take a look 

Chris, 
The site does not have the GTM or GA tag yet. 
I cannot confirm Google search console without it. 
Here's the HTML tag just in case you want to provide it to their developer. 

<meta name="google-site-verification" content="4YO4L16UOM1yRMXiTuBSYlBzAJtQ1h5aL5SMyzqgjL0" />

Hector  - I had added the verification code.

Isaac,
Good morning.
I am getting an error on the verification -

Hector  - I just verified it for you. Thanks.

I see it as now verified, thanks Isaac. 

We are good to go here.
