There's a couple different ways you can manage them. Are we talking about raised beds?
With everbearers, they will grow multiple crowns and make more and bigger berries on the mother plants. You can start with your mother plants and keep them up to 5 years, removing all runners, then start a new bed to replace them before they're done, starting their replacements every 4th year. Or (what I think is better) you can take runners (or buy new plants, if you're concerned about disease problems with the originals) and start a new row every year, adding a row each year until you get up to five rows. Then when you get to year 6, tear out all the first row plants and put new plants into that row. Year 7, you would put new plants into year 2's row, so on and so forth. For each newly started row, the spring blooms should be pinched off and not allowed to set fruit (late summer/fall crop is ok). Remove all runners too (except to allow a few to get going as replacements).
Junebearers are handled in an entirely different manner. They are best grown in a flat garden area that you can get into with a tiller. Runners are unstoppable and prolific, but that's ok, because they will grow next year's berries. The mother plants spend most of their energy making runners will make berries the next year, but not nearly as well as the established runners will. So year one with them, you want to pinch all spring runners until the new plants are strong, then let them spend the rest of the summer making runners like crazy. I'll have to double check, but I think spacing is 18" apart each and 3 feet apart rows for the mother plants. The runners will fill in everywhere making what they call a matted row. Next year you would go in with the tiller and till under the original mother plants leaving a row of runners which you will pick your berries from. Same thing the following year, allow runners to go and till the secondary mother plants under.
This is off the top of my memory, but try reading Gene Logsdon's
Successful Berry Growing for more details and diagrams. This is an indispensible book IMO and it covers all types of berries in depth.
