All SiteGround Accounts are Now Using Site Tools

Mission Accomplished! The last one of our cPanel servers was switched to Site Tools yesterday. We are so excited to see this long and complex migration come to an end as now each and everyone of our customers is safely brought to the new era of SiteGround development. A year and a half ago we started the transition from a 15-year old server setup, dominated by third-party software that was inevitably putting reins on many of our boldest dreams, to the new state-of-the-art hosting management platform, driven by our own unique server software. Since we launched our first server on the new platform in 2019, we were finally able to unleash the full potential of our imagination and we have already created a lot of speed, security and usability improvements that would have never been possible with the old platform. And, we know that the best is yet to come!

The idea and vision for our new cutting-edge platform was born about 4 years ago and soon after, we dived into building SiteGround’s Site Tools and new Client Area. We started onboarding new clients to it in the summer of 2019, but switching all our existing clients was a hugely complex task that took us another 1.5 years and tons of hard work. Here’s a glimpse of all the effort that went into this complex migration process to explain why this is such a milestone and a proud moment for us.

Large Number of Accounts and over 3367.46 TB of Data Migrated 

The huge amount of live hosting accounts and website data that had to be transferred from servers with cPanel to servers with Site Tools setup was a fundamental part of the challenge. Performing such a massive operation successfully required a meticulous organization of manpower and resources. During the past 1.5 years our management team spent countless hours coordinating teams and shuffling resources to ensure that we are migrating away from cPanel in the fastest and safest way possible for our clients. To sum it all up, we transferred a total of 15 774 servers with 3367.46 TB of data on them in the period from September 2019 to April 2021, and that is a huge deal! 

A Multitude of Use Cases and 44,000 Lines of Code Written for Migration Automations

Besides the large volume of data, the second biggest challenge was the multitude of edge cases that had to be reviewed and addressed with a solid technical solution – multiple applications set to use absolute paths in their configuration; websites with either addon, parked or subdomain infinite setup option; multiple addon domains using the same database; and more! Our DevOps, Software Engineers and Technical Support teams all had to dig deeper into identifying, analyzing, and providing a solution for each of those cases. Once we identified them and crafted an efficient solution for each, we got to automate it. Our DevOps would write scripts for pre-migration checks to detect matching potential issues on a server, call special migration rules for them, and then run post-migration checks to make sure nothing was broken. If anything did go wrong, we would audit the scripts and get back to coding to improve them. In addition, in case of any issues with the automations, our Technical Support representatives would take over by running manual website checks and fix them.

We had 35 of our experts in charge of writing migration scripts, iterating, testing, and enhancing their code over and over until we made them as fast and efficient as possible. Together, these dedicated professionals lived and breathed this project every day, writing 44,000 lines of code in total to get us where we are today.

Our Best Record: 8985 Accounts Migrated in One Day 

In the beginning, we were shyly moving at a few hundred account transfers per day with a high fail rate, meaning we had to go over many of them manually and fix any issues that might have been caused by the migration. Thanks to the constant improvement of our scripts and our admins’ growing expertise, we managed to speed up the process tremendously and drop the fail rate significantly. It all led up to our record-breaking day – March 7, 2021 when we migrated 8985 accounts in a single day!

60,000 Hours Invested in Manual Post-migration Verification

Another big challenge was our determination to move all of the accounts in the shortest time possible without affecting the availability and functioning of the sites. As explained above, manual checks were an intrinsic part of the process, no matter how much the fail rate was dropping. We counted 60,000 human hours in total distributed among 160 000 accounts that were audited for post-migration issues and manually fixed after.
