    Hi

    I am looking for download links to get some older versions of 3CX

    We have been using an old V11 and recently got a virus which corrupted most files

    I have installed the original V11 and taken a fresh backup from the original
    This has worked but didn’t import the licence and won’t connect to the browser to check the licence or updates

    I have updated our licence to a V15 annual
    Licence which I have been going to do for some time
    Now i just need to restore from the old V11 backup

    I believe i will need upgrade the original starting with V11 service pack 4 upwards

    Thanks
    Richie

    Thanks Craig,

    Unfortunately V12 wont accept the backup from V11
    The 3CX upgrade document suggests the following

    • From v9 and v10 you must upgrade to v11 SP 4a first, then to v12 SP 6.1
    • From v12 SP 6.1 you must go to v12.5 first. *
    • From v12.5 SP2 you can go to 15(.5) *
    • From v14 SP3 you can go to v15(.5) directly.
    It looks live I may need V11 SP4a first

    Thanks
    Richie.

    I'll check and see if I have a copy of the v11 with SP4a for you.
