Advent cloud hosting: APX, Axys, and Moxy
Running Advent products on-prem means your team handles upgrades, patches, and the occasional 11 PM crisis before month-end close. We have been hosting Advent applications since 2005. We know the upgrade paths, the gotchas, and the reporting schedules these products need to support.
- Hosting Advent products since 2005 across APX, Axys, and Moxy
- Product upgrades handled by our team, not yours
- Retainer-based support with allocated monthly hours

Who this is for
Firms running Advent products that want somebody else to handle the infrastructure and upgrades. That is the short version. Here is the longer one.
Firms falling behind on Advent upgrades
If you are two or three versions behind on APX or Axys because nobody has time to plan and test the upgrade, that is exactly what our hosting support covers. We schedule upgrades, test them, and roll them out.
Firms where IT support is stretched thin
When your IT person also handles compliance, vendor management, and office networking, Advent product issues fall to the bottom of the list. Offloading the hosting and support side gives them room to breathe.
What you get with CSSI Advent hosting
Hosting is the foundation, but the real value is what comes with it. CSSI cloud customers get support hours, upgrade services, and escalation paths that are built around Advent products specifically.
Product upgrades for APX, Axys, and Moxy
We handle the upgrade process from planning through testing and deployment. You stay current without pulling your own team off other work.
Report troubleshooting and issue resolution
When a report breaks or data looks wrong, our support team knows these products well enough to diagnose the problem directly, not just forward it to SS&C.
Escalation support with SS&C
When an issue does need to go to SS&C, we manage that escalation. We know how to file tickets that get attention and follow up until they are resolved.
Flexible retainer-based support
You get allocated monthly hours for support and upgrades. Use them for report troubleshooting one month, upgrade planning the next. The hours flex with your needs.
Getting your Advent environment into the cloud
We have migrated APX, Axys, and Moxy environments many times. The process follows a pattern because we have worked through the edge cases already.
- Inventory your Advent setup. Which products, what version, how many users, what custom reports or integrations exist.
- Build the cloud environment. We configure the hosted environment to match your current setup, including any related tools that need to come along.
- Validate everything. Your team tests access, performance, and reporting workflows before we cut over.
- Go live and upgrade if needed. Once you are live, we can also bring you current on product versions if you have fallen behind.

FAQ
Can you host APX, Axys, and Moxy together?
Yes. Many firms run more than one Advent product. We host them in the same environment so everything works together the way it does on-prem.
Do you handle Advent upgrades?
Yes. Upgrade services for APX, Axys, and Moxy are part of the hosting support. We plan, test, and deploy upgrades on your behalf.
What if we are several versions behind?
That is common. We can bring you current as part of the migration or phase upgrades over time, depending on what makes sense for your team.
How is this different from hosting with SS&C directly?
CSSI is an independent hosting provider with Advent product expertise. You get dedicated support, flexible retainer hours, and a team that knows both the infrastructure and the applications.
