SAP provides well-defined upgrade paths for SAP Business One. Direct upgrades from one SAP Business One release to another are normally only supported if the currently installed release and target release are two consecutive releases (e.g. upgrading from 2007 to 8.8).
Depending on technical constraints, if the currently installed release and the target release are more than one version apart (for example, 2007 to 9.2), upgrades may have to be performed in several steps.
An exception applies to the SAP Business One release families. Direct upgrades are supported in the following scenarios:
Refer to the SAP Business One Upgrade Strategy for an overview of upgrade options.
SAP Business One delivers solutions for defects reported by partners and for key legal changes. A patch cumulates solutions and delivers them as one package in a defined frequency for a release. Patches are necessary to provide prompt solutions to reported defects and regressions and stabilizes the product over time. As the release matures, the frequency of patch releases decreases in order to lower the patching effort for partners and customers.
In exceptional cases, a solution to a specific issue must be delivered outside of the defined patch cycle. The hot-fix mechanism enables SAP Business One to deliver the required solution to customers/partners immediately, without having to wait for the next patch release.
In very exceptional and rare cases, a hot-fix delivers a solution to a problem that was caused by a previous patch. This hot-fix would be announced by hot news or other specific roll-out communication.
Once a hot-fix is applied to the customer's installation to correct the issue, it is recommended to update to the next regular patch once released, as hot fixes are only provided as temporary solutions. If a hot-fix is not applicable to all customers, it is not necessary to install the hot-fix because the next regular patch will include that particular hot-fix.
