Hi there,

WHMCS have again pushed out the end-of-life date for WHMCS v8.13, this time to 31st January 2027.

It seems likely that they will stick to the date this time, following vulnerabilities in the software found prior. Due to that, we’ve scheduled this maintenance window to perform major upgrades from WHMCS v8.13 to v9.x.

As this is a major upgrade, we’ve booked this maintenance window to ensure it’s covered for visibility. By the time of the upgrade, it’s likely we will be upgrading WHMCS v8.13.x to v9.2.x (currently v9.0.x). Due to the nature of WHMCS being “hit and miss” with regard to reliability, we only use their Long Term Support (LTS) versions.

• Summary of Versions: https://docs.whmcs.com/releases/
• https://docs.whmcs.com/about-whmcs/whmcs-development/
• https://docs.whmcs.com/releases/updating-through-eol-versions/

Please let us know if you have any questions, concerns or curiosities about this upgrade work.

Cheers,
Merlot Digital
