I have a small office network of 4 Pentium PCs, all 5-7 years old, running Win 98 2nd, and peer-peer Windows network using coax cable without a hub. I use the old Microsoft Mail program to share Outlook folders. I do all my own software and hardware installation, and have been periodically upgrading components and software for 18 years, but I am not a "professional." Everything still works well enough, although slow in some cases, but we are having to install new software that will require upgraded PCs. What is the best way to replace all 4 PCs and install a network hub with an internet router, etc and move most of the applications, data, Outlook, email, etc. on the old PCs to the new ones with a minimum of headaches? I will need to do all this over a weekend. Is there a website I can go to for basic advice about upgrading? Is there software which might be helpful? Thanks.
