Azure CSP Resource Move

Grey Matter helps Muhimbi move from Azure pay-as-you-go to CSP for more flexibility and cost savings


Muhimbi, a PSPDFKit company, is a global leader in automatic PDF conversion. Trusted by enterprises, their software offers a comprehensive suite of PDF tools for SharePoint and Power Automate, featuring an intuitive online app. 

Sectors: Technology

Vendors: Microsoft

Products: Microsoft Azure



Muhimbi needed an easier way to manage Azure subscriptions and usage. When acquired by PSPDFKit in 2022 the need for external support to deliver the project became even more urgent.


Grey Matter’s services division, Climb Global Services (CGS), carried out this project. CGS has a team of Azure accredited engineers and architects.  

CGS began by discussing the requirements, creating a Statement of Works, and outlining the responsibilities for both CGS and Muhimbi, so that there was a clear understanding from both sides. 

Our Cloud and Infrastructure Engineer moved all Muhimbi’s Pay-as-You-Go (PAYG) moveable resources to a new CSP Subscription. This involved some downtime as several of their app services have SSL Certificates attached to them, that needed to be unattached before moving and re-attached once they had been moved.

The downtime was limited to the weekend dates as agreed with Muhimbi and all non-service impacting actions took place on a Friday. Following this, the remainder of the resources were moved on a per Resource Group basis.  

In addition, some of the technical team from Muhimbi attended Grey Matter’s yearly ISV Partner Day event. 


There was very little downtime during the project, and when there was, it was outside of normal office hours meaning employees and customers were not affected by the project. 

Muhimbi now has more control and flexibility over their Azure subscriptions. 

By attending ISV Partner Day, Grey Matter’s annual Microsoft partner event, Muhimbi team members have been able to learn more about Azure (both technical and commercial aspects), and how Grey Matter and Climb Global Services can support them further with Microsoft licensing and support, and other solutions.

Grey Matter and Climb Global Services are professional, knowledgeable, and give good advice. They did the work, and it was a painless experience. Elijah was a big help. He split the project in two, making it a lot easier to manage.
