Hi, I have the same issue in Step7 — I only have the 6ES7 350-1AH02-0AE0 module, but for the migration project from SM to TIA, I need the 6ES7 350-1AH03-0AE0 version. I found only this link for the firmware update: https://support.industry.siemens.com/cs/document/16812649/firmware-update-for-fm350-1-(6es7350-1ah03-0ae0)?dti=0&lc=en-PL?dti=0&lc=en-PL)

However, when I download the file, the system flags it as suspicious. Has anyone else experienced this issue? Is there any alternative solution? I'm using Step 5.7 + SP3
