HOW TO: Upgrade the flaik Resort API to 2.6.0

Install Folder for Current releases.

Upgrading from 2.5.11 (or any earlier 2.x) to 2.6.0

Version 2.6.0 ships a rebuilt MSI installer that installs to a new location (C:\Program Files\Flaik\Flaik POS Integration API\; previously C:\Program Files\Flaik Resort Service\). Because the location changes, your existing configuration is not carried across automatically — capture it first, then reconfigure after install.

We are available to run this upgrade with you — book a session via the link in your upgrade email.

Step 1 — Record your current configuration

Open C:\Program Files\Flaik POS Integration API\appsettings.json on the resort machine and record these values from the FlaikServiceSettings section:

Field	Key
flaik DB connection string	FlaikDatabaseConnectionString
Resort/POS DB connection string	ResortDatabaseConnectionString
POS software code	ResortPosSoftwareCode (RTP One = 1, Siriusware = 2, InTouch = 5, Guest Connect = 8)
Install identifier	InstallIdentifier
Custom listen port, if you changed it	Kestrel.Endpoints.Http.Url (default 8001)

Also note any non-default values in your provider file (appsettings.rtpone.json, appsettings.siriusware.json, or appsettings.intouch.json).

Do not copy ApiKey. The stored value is encrypted to the old installation and cannot be reused. The new version generates a fresh key on first start and flaik central picks it up automatically.

Step 2 — Uninstall the old version

Stop the Service and then uninstall "Flaik POS Integration API" via Settings → Installed Apps, or from PowerShell:

$code = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\*" |
         Where-Object DisplayName -eq "NAME OF YOUR FLAIK INSTALL").PSChildName
msiexec /x $code /qb /l*v uninstall-old.log

The old installer intentionally leaves appsettings.json behind at the old path. Once Step 1 is captured, delete the leftover folder:

Remove-Item -Recurse -Force "C:\Program Files\FLAIK FOLDER"

Step 3 — Install 2.6.0

Run Flaik.POS.Integration.Installer.2.6.0.msi (or the .Staging. MSI for staging). In the wizard, select your POS software type and enter your site identifier on the flaik configuration screen — use the values recorded in Step 1.

Step 4 — Apply the captured configuration

Open C:\Program Files\Flaik\Flaik POS Integration API\appsettings.json and paste the recorded values into FlaikServiceSettings. Leave ApiKey empty. If you had a custom listen port, set the Kestrel__EndPoints__Http__Url environment variable for the service rather than editing environment config files (those are replaced on future upgrades).

Step 5 — Run the database scripts

Execute the SQL scripts from C:\Program Files\Flaik\Flaik POS Integration API\SQL\: the flaik scripts plus the subfolder matching your POS (RtpOne\, Siriusware\, ...). 2.6.0 updates the flaik database version to 2.6.0.0. Contact flaik support if you'd like these run together.

Step 6 — Restart and verify

Restart-Service FlaikResortService

Browse to http://localhost:8001/health (production) or http://localhost:8002/health (staging). Confirm:

• the reported version is 2.6.0, and

• the provider configuration section shows a PosSoftwareVersion value (new in 2.6.0).

If the port is exposed externally, re-test the external URL and firewall rule.

Upgrading between 2.6.x versions (future patches)

From 2.6.0 onward, upgrades are in-place again: run the newer MSI and it upgrades the existing installation directly. Your appsettings.json and provider config files are never overwritten — no capture/re-entry step. flaik-managed defaults (appsettings.flaik.json and the environment file) are refreshed automatically as part of the upgrade.
