This page deals exclusively with standard uniCenta oPOS versions.
If you have a non-official version from another source you should refer to that supplier.


uniCenta oPOS version 4 has two upgrade routes:

  1. Automatically upgrade from the following previous versions in one step
  2. Database Transfer

In both cases upgrades include version 3.70 through to 3.91.3



  • APACHE DERBY – Embedded & Client/Server
  • ORACLE 10/11g Express

When upgrading, the installer has no way of knowing what may have been changed from standard, so what is there at upgrade time is left as is and not over-written. Only new scripts and ticket templates are added.
For example : to take advantage of the new multi-destination remote print feature a manual change to your existing Printer.Ticket is needed.


The Menu.Root file is replaced so that the new modules and feature changes are available.

ROLES (Permissions)

The Administrator account is over-written to incorporate  the new Menu and feature changes. All other Roles permissions are left un-touched and other Roles will need to be amended manually to access the new features.


All reports and accompanying script files are over-written with new versions.


Several new ticket templates have been introduced, for example; product multi-destination remote printing. These are added automatically during installation and existing ticket templates are left intact to preserve any changes that have been made.
Manual update of existing ticket templates is needed to take advantage of the new remote printing functionality if the auto-upgrade option is used.


At this time the only fully implemented languages in uniCenta oPOS v4 are:

  • English UK (default)
  • English USA
  • French

Where other included languages are not fully translated English (UK) will show as this is the default text setting for all labels and messages that may have been introduced since the version you are upgrading from. There are more than 400 new label and message additions in v4 compared to version 3.91.3
