Minor upgrades are free. You apply them and they will work.
However, if patches are involved, the upgrade will not work unless the patch is included into the next release or reinserted into the current and that takes some labour time.
For example, if you want to upgrade to PBXware 3.8.5 but you have patches that are not included in that release, we would need to:
- Remove the patches
- Do the install
- Reapply the patches
This would result in a support fee typically of half-day. You may prefer to wait until the patch is included in a following release.
However if the patches no longer work with the new Edition, this may require a complete re-work of the patch. This would be quoted for before work commenced.
