# Salesforce Upgrades and Maintenance

Salesforce reserves up to five minutes of service interuption for major upgrades, but you have access your data during other maintenance events, like splits and migrations.

- **[Read-Only Mode](https://help.salesforce.com/s/articleView?id=xcloud.setup_maintenance_mode_overview.htm&release=264.0.0&type=5)**  
    Access to your data at a moment’s notice—even during our planned maintenance windows. To minimize interruption to your business, Salesforce gives users read-only access during splits, instance migrations, instance switches, pre-scripts, and certain other maintenance events.
- **[5 Minute Upgrades](https://help.salesforce.com/s/articleView?id=xcloud.five_minute_upgrade.htm&release=264.0.0&type=5)**  
    Salesforce reserves just five minutes of scheduled maintenance time to roll out new major versions of our service. These upgrades to the next release occur three times per year.
- **[Check for Desktop Client Updates](https://help.salesforce.com/s/articleView?id=xcloud.usersetup_checkforupdates.htm&release=264.0.0&type=5)**  
    Desktop clients such as Salesforce for Outlook and Connect Offline integrate Salesforce with your PC. Your administrator controls which desktop clients you are allowed to install.
