# Problems Staying

The decision to stay put on your old version of Dynamics 365 Finance and Operations instead of upgrading to v8.1 is a bold one. However, we guess you know that.

## Sorry to play the doom and gloom card, but here’s what you can look forward to:

- What you’ve got, is what you’ve got. No more upgrades, period. The feature-set will be frozen to current application level
- Kiss your support goodbye. As of 1 April 2019, there won’t be any more hot-fixes from [Microsoft.](https://www.fusion5.com/au/microsoft/ "MICROSOFT") And as the support contract has finished, they’re under no obligation to fix your – or anyone else’s issues.
- Lack of surety. You’ll have no guarantee for uptime / availability.
- Compatibility crises. Backend services (Azure SQL) could break compatibility — as has been seen with TLS 1.2 version requirements.
- Stuck in time. You won’t have any access to newer ISV options.
- An expensive future. If you don’t upgrade now, you’ll find that a future upgrade will be expensive and require extensive testing / re-implementation.
It doesn’t take much reading between the lines to see that we don’t recommend staying put on v7.3.

In just four to six weeks¹ we can get you upgraded to [Dynamics 365 Finance and Operations](https://www.fusion5.com/au/microsoft/dynamics-365/finance/ "ERP Finance") v8.1 and looking good.

¹ Timeframe depends on a number of factors, any existing code over-layering will require additional time to move to extensions.
